The side lengths of a 30-60-90 triangle are in the ratio 1:13: 2. What is
tan 60°?
A
=============================================================
Work Shown:
Refer to the diagram below. The short leg (opposite the 30 degree angle) is equal to 1 unit, the long leg is equal to sqrt(3) units, and the hypotenuse is 2 units long.
For the reference angle 60 degrees, the opposite leg is sqrt(3) units and the adjacent leg is 1 unit
tan(angle) = opposite/adjacent
tan(60) = sqrt(3)/1
tan(60) = sqrt(3)
Answer: tan 60° = √3

degrees
9514 1404 393
Answer:
∠S = 117°∠R = 63°x = 35Step-by-step explanation:
Because this is an isosceles trapezoid, you know right away that angle S is the same as angle T, so angle S = 117°.
In order to find x, we need to know angle R. Angle R is the supplement of angle S, so ...
angle R = 180° - angle S = 180° -117°
angle R = 63°
Knowing this, we can find x:
(2x -7)° = 63°
2x = 70 . . . . . . . . . divide by °, add 7
x = 35 . . . . . . . . . . divide by 2
_____
Additional comment
Of course, angle V = angle R = 63°. We give you all of the angles in addition to the value of x, because there are obviously different versions of this question. (Your text asks for angle S; the picture asks for angle R.)

Mike and Shawna are selling cookie dough for a school fundraiser. Customers can buy packages of chocolate chip cookie dough and packages of oatmeal cookie dough. Mike sold 12 packages of chocolate chip cookie dough and 3 packages of oatmeal cookie dough for a total of $225. Shawna sold 6 packages of chocolate chip cookie dough and 11 packages of oatmeal cookie dough for a total of $293. What is the cost each of one package of chocolate chip cookie dough and one package of oatmeal cookie dough?
Answer:
$19 for one package of oatmeal cookie dough and $14 for one package of chocolate chip cookie dough
Step-by-step explanation:
We need to set up two equations: one that shows how much money Mike made and one that shows how much money Shawna made.
Let's make a = price for one chocolate chip cookie dough and b = price for one oatmeal cookie dough.
First equation for Mike: 12a + 3b = 225
Second equation for Shawna: 6a + 11b = 293
Next we isolate b from Mike's equation: b = 75 - 4a
Then we plug this equation into Shawna's equation and we get:
6a + 11(75 - 4a) = 293
Solving for a would get us 14, or $14 for one chocolate chip cookie dough.
If we plug 14 = a into Mike's original equation and solve for b, we get b = 19, or $19 for one oatmeal cookie dough.
Hope this helped!

Answer:
E and F
Step-by-step explanation:
✔️One of the angles of the triangle given has a measure that is above 90° (120°). An obtuse triangle triangle has an angle measure that is above 90°. Therefore, the triangle above is an obtuse triangle.
✔️All three angles and sides are of unequal measure, therefore, this can be referred to as a scalene triangle. A scalene triangle has 3 unequal angles.

Answer:
3/4a-1/3b
OR
-1/3b+3/4a
Step-by-step explanation:
copy this and translate it, because I can't talk this language
add like terms 1/2a+1/4a=2/4a+1/4a=3/4a
then you write -1/3b itself because it don't have like terms
the final answer will be:
3/4a-1/3b
OR
-1/3b+3/4a

solve the equation by using trial and error method 6 - x =2
Answer:
x = 4
Step-by-step explanation:
The given equation is :
6 - x =2
Put x = 1 and see LHS is equal to RHS or not.
So,
6-1 ≠ 2
Put x = 2 and see LHS is equal to RHS or not.
So,
6-2 ≠ 2
Put x = 3 and see LHS is equal to RHS or not.
So,
6-3 ≠ 2
Put x = 4 and see LHS is equal to RHS or not.
So,
6-4=2
2 = 2
So, the solution of the given equation is x = 4.
A group of students organized a car wash to raise money for a local charity. The students charged $5.00 for each car they washed. In 3 hours, they washed 12 cars. At that rate, how much money could they earn from washing cars for 9 hours?
The students will earn $180 by washing cars for 9 hours.
In 3 hours the students will earn...
$5 x 12 = $60
5 dollars x 12 cars = 60 dollars
So in 3 hours the group of students will earn $60
In 9 hours the students will earn...
$60 x 3 = $180
Since the students will earn $60 per every 3 hours, you multiply $60 with 3 because if you divide 9 hours by 3 hours you will get 3. The answer you get by multiplying 60 by 3 is 180. Therefore the students can earn $180 from washing cars.
I hope this helps!

Answer:
Step-by-step explanation:
Because this is a quadrilateral, all the angles added up together will equal 360 degrees. By the nature of the quadrilateral, opposite angles are supplementary. Therefore, 180 - 115 will equal angle K:
180 - 115 = 65 degrees

Answer:
Mike can buy 7 model cars

Water is placed in a cellular bucket on a bench The book has a diameter of 12 in and a height of 12 in The bucket is capable of supporting a max of 200 lb water weights about 64.2 ft³ how much does a water in the bucket weigh
Answer:
bucket of water = 50.397 lbs
Step-by-step explanation:
Pi(r^2)(h) = volume
3.14(6^2)(12) = 1356.48 in^3 = volume of bucket
one ft^3 = 12 x 12 x 12 = 1728 in^3
1356.48/1728 = 0.785 ft^3 (volume of bucket)
0.785(64.2) = 50.397 lbs

The unit prices and quantities for two goods for two years
are shown in the table below. Assume that consumers are

2.00
3.00
Answer: $28
Step-by-step explanation:
The price of water in Year 1 is $1 per unit. There are 8 units so their value is:
= 8 * 1
= $8
Price of a loaf of bread is $2. The basket contains 10 loaves of bread. Value is:
= 10 * 2
= $20
Total value of the basket in year 1 is:
= 20 + 8
= $28

If it costs £55 to buy 11 cushions, how much will it cost to buy 19?
Answer:
£95
Step-by-step explanation:
Cost of 11 cushions = £55
Unit cost of 1 cushion = 55/11 = £5 per cushion
Cost of buying 19 cushion = 19 × unit cost
= 19 × £5
= £95
Thus, it would cost £95 to buy 19 cushions
Step-by-step explanation:
11 cushions = £55
1 cushion = 55 ÷ 11
1 cushion = £5
19 cushions = £5 × 19
= £95
