Please help how do you solve this?
Answer:
A, 120 degrees
Step-by-step explanation:
=============================================================
Explanation:
Triangle ABC is equilateral, so all three sides are the same length. This means the three angles are also the same measure. Call each interior angle x.
The three angles add to 180, so x+x+x = 180 solves to x = 60. Each interior angle is 60 degrees.
Angle DAC is an exterior angle of measure 180-x = 180-60 = 120 degrees
------------
Or another method you could use is the fact that all exterior angles of any polygon add to 360.
Since we have n = 3 sides, this means each exterior angle of an equilateral triangle is 360/n = 360/3 = 120 degrees
We consider this a regular polygon because all sides are the same length and all angles are the same measure. So the formula for the exterior angle measure 360/n would apply to any regular polygon and not just triangles.

Solve the inequality.
−78≤m−138
The solution is
Answer:
M = 60
Step-by-step explanation:
You are doing the opposite to each side to simplify the inequality so on one side it is the variable in your case, it is m and the other side is your number. You are going to add 138 to both sides and then you get your answer.
-78 ≤ M - 138
-78 + 138 ≤ M - 138 +138
60 ≤ M
=
M ≥ 60

Answer:
( -1, -1 )
Step-by-step explanation:
Just multiply the scale factor with the coordinates
-3 × [tex]\frac{1}{3}[/tex]
= [tex]\frac{-3}{3}[/tex]
= -1
So the coordinates are :
( -1, -1 )

On a coordinate grid from negative 6 to positive 6 on the x-axis and on the y-axis, two points A and B are shown. The point A is on ordered pair negative 4, 5, and the point B is on ordered pair 5, 5.
If the area of the rectangle to be drawn is 90 square units, where should points C and D be located, if they lie vertically below A and B, to make this rectangle?
1. C(4, −5), D(−3, −5)
2. C(5, −4), D(−4, −4)
3. C(5, −5), D(−4, −5)

Answer:
D! See explanation below!
Step-by-step explanation:
D is absolutely correct!
And I'll explain why:
The area of the trapezoid is (lower base + upper base) times (height) divide 2
So:[tex](4+7)(8)/2\\=11(4)\\=44 (cm)^{2}[/tex]
The area of the Triangle is (Base)(Height)/2
So:[tex](6)(10)/2\\=30(cm)^{2}[/tex]
Well, 44 is larger than 30, so the answer's D!!!

Ginny bought 2.2 pounds of bananas at a cost of $0.49 per pound and 1.3 pounds of grapes at a cost of $1.29 per pound. What was the total cost of the bananas and grapes Ginny purchased?
Answer:
$2.76
Step-by-step explanation:
Price per pound times the number of pounds Ginny bought
Bananas:
2.2*0.49 = 1.078 -> 1.08
Grapes:
1.3*1.29 = 1.677 -> 1.68
Now, to find the total cost of both, add the prices together
1.08 + 1.68 = 2.76
Answer:
$2.76
Step-by-step explanation:
one pound of bananas cost $0.49 , multiply this cost by 2.2 to find the cost at this weight.
2.2*0.49=1.078=1.08
1.3*1.29=1.677=1.68
1.08+1.68=2.76

TROLL FOR POINTS= REPORT
CORRECT ANSWER= BRAINLIEST
Answer:
2 days
Step-by-step explanation:
We need to pay $63.68 per DAY and $0.10 per MILE, while staying BELOW the budget of $170... therefore,
$63.68d + $0.10m < $170We are also already given m, which is 250 miles (The amount she plans to travel.) Solve for d.
$63.68d + $0.10(250) < $170$63.68d + $25 < $170$63.68d < $145d < 2.777In other words, the theoretical maximum amount of time she can rent before exceeding her budget is 2.777 days. That's not practical though so we will round the final answer DOWN to 2 days to be safe and stay within budget.

A ladder 3m leans against a wall. The foot of the ladder is 80cm from the wall. The distance the ladder reaches up the wall is:
Answer:
d
Step-by-step explanation:
hope this helps :)
The distance the ladder reaches up the wall is 289 cm. The correct option is E 289 cm
Pythagoras' theoremThe Pythagoras' theorem states that, in a right triangle, the square of the hypotenuse equals the sum of the squares of the other two sides
Let the length of the ladder be l
The distance of the foot of the ladder from the wall be f
and the distance the ladder reaches up the wall be h
By applying Pythagoras' theorem, we can write that
l² = f² + h²
From the given information,
l = 3m = 300 cm
f = 80 cm
Putting the parameters into the equation, we get
300² = 80² + h²
90000 = 6400 + h²
Then,
h² = 90000 - 6400
h² = 83600
∴ h = √83600
h = 289.1366
h ≅ 289 cm
Hence, the distance the ladder reaches up the wall is 289 cm. The correct option is E 289 cm
