Find the values of the sine, cosine, and tangent for angle A
Answer:
sin = p/h.
cos=b/h
tan =p/b
pythagoras
h^2=p^2+b^2
here
h=5
p= 3
b=4
Answer:
sin(A)=3/5
cos(A)=4/5
tan(A)=3/4
Step-by-step explanation:
length of the other side is 5 using pythagorean theorem
sin= opposite/hypotenuse
cos= adjacent/hypotenuse
tan= opposite/adjacent
opposite angle A- 3
adjacent angle A- 4
hypotenuse- 5

Which statement is not correct?
A. The terminal side of a 45° angle is in quadrant I.
B. A 95° angle is an acute angle.
C. A 210° angle is a reflex angle.
D. A 125° angle is an obtuse angle.
Answer:
b.) because it is over 90*
Step-by-step explanation:
Solve for x: -2x + 1 = -6
This is a 2-step equation. We will solve it in 2 steps.
[tex]-2x + 1 = -6\\\\-2x = -7\\\\x = \frac{7}{2}[/tex]
The solution for this equation is x = [tex]\frac{7}{2}[/tex].
A taxi driver can cover a distance of 130.16 miles per gallon per 5 gallons of gas if the same taxi driver travel 60 miles at the same miles per gallon the second day what would be the best estimate of number of gallons a taxi driver use
Answer:
[tex]Gallons = 2.305[/tex]
Step-by-step explanation:
Given
Rate = 130.16 miles for 5 gallons
Required
Number of gallons used for a journey of 60 miles
The rate in miles per gallon is calculated as:
[tex]Rate = \frac{Distance}{Gallons}[/tex]
When distance = 130.16 and gallons = 5, we have:
[tex]Rate = \frac{130.16}{5}[/tex]
[tex]Rate = 26.032[/tex]
When distance = 60 miles.
Substitute 60 for distance and 26.032 for rate in [tex]Rate = \frac{Distance}{Gallons}[/tex]
[tex]26.032 = \frac{60}{Gallons}[/tex]
Cross Multiply
[tex]Gallons * 26.032 = 60[/tex]
[tex]Gallons = \frac{60}{26.032}[/tex]
[tex]Gallons = 2.305[/tex] --- approximated

Help me pls, for number 19, I have absolutely no idea what I’m supposed to do.
All you have to do is take the value listed above for g(x) and set it equal to 16.
-3x+1=16.
Subtract 1 from both sides
-3x=15
divide both sides by -3
x=-5
Line d passes through points (10, 10) and (7, 5). Line e is perpendicular to d. What is the slope of line e?
Simplify your answer and write it as a proper fraction, improper fraction, or integer.
Answer:
(-3,-5)
Step-by-step explanation:
subtract y1 from y2 and you get -5. Now subtract x1 from x2 and you get -3. Now put the x value first and then the y value.
Answer:
m =5/3Step-by-step explanation:
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}\\\\\left(x_1,\:y_1\right)=\left(10,\:10\right),\\\:\left(x_2,\:y_2\right)=\left(7,\:5\right)\\\\m=\frac{5-10}{7-10}\\\\Simplify\\\\m = \frac{-5}{-3} \\\\m=\frac{5}{3}[/tex]
QUESTION: find the perimeter
Answer:
4g + 4
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Length = 0.7g + 2
Width = 1.3g
Plug in the values into the equation
Perimeter = 2(0.7g + 2 + 1.3g)
Perimeter = 2(0.7g + 1.3g + 2)
Perimeter = 2(2g + 2)
= 2*2g + 2*2
Perimeter = 4g + 4
simplify (8 x k) x 4

Answer:
The value of x is 67
Step-by-step explanation:
If two adjacent angles formed a line, then they called a pair of linear anglesThe measure of the pair of linear angles is 180°In the given figure
∵ One side of the triangle is extended to form an exterior angle of 113°
∵ The angle of 113° and the angle of x° are adjacent angles
∵ They formed a line (the side is extended)
→ That means they formed a pair of linear angles
∴ The angle of 113° and the angle of x° formed a pair of linear angles
∵ The measure of the pair of linear angles = 180°
∴ 113° + x° = 180
→ Subtract 113 from both sides
∵ 113 - 113 + x = 180 - 113
∴ x = 67
∴ The value of x is 67
SAT QUESTION!!!
Jayden has been reading a 275-page book for English class. On average, he has read about 10 pages in 15 minutes. With a deadline looming, Jayden realizes that he won't finish in time unless he skims through the rest of the book. If he skims the book, he can cover 15 pages in 10 minutes. If it takes Jayden 5 hours and 50 minutes to finish the book (reading and skimming combined), how many pages did Jayden have to skim through?
WITH STEPSSS
Step-by-step explanation:
Let x be the number of pages that were skimmed through.
Time taken to skim through = 10 * (x/15) = 2/3 x min.
Time taken to read through = 15 * [(275-x)/10] = 1.5(275-x) min.
We have 2/3 x + 1.5(275-x) = 350.
Therefore 412.5 - 5/6 x = 350 and x = 75.
Answer:8pages
Step-by-step explanation:
10minutes/350minutes×275=7.85~8pages

Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $30 monthly fee and charges an additional
$0.14 for each minute of calls. The second plan has a $22 monthly fee and charges an additional $0.19 for each minute of calls. For how many minutes of calls
will the costs of the two plans be equal?
Answer:
The plans will be equal at 160 minutes of call
Step-by-step explanation:
1st plan: y = 0.14x + 30
2nd plan: y = 0.19x + 22
0.14x + 30 = 0.19x + 22
Subtract 0.19x from both sides;
-0.05x + 30 = 22
Subtract 30 from both sides;
-0.05x = -8
Divide both sides by -0.05
x = 160
