tan(angle) = opposite/adjacent

tan(B) = AC/AB

tan(B) = 9/7

B = arctan(9/7)

B = 52.125 which is approximate

B = 52

--------------------------------------

The final answer is choice D) 52 degrees

Find the measure of the exterior angle.
AveGali [126]

Answer:

110°

Step-by-step explanation:

t+(t+10)+(t+20)=180

t+t+10+t+20=180

3t=180-10-20

3t=150

t=50°

t+20=50+20

=70

180-70=110°

8x(5+10)= (8x5) + (5x10)
Slav-nsk [51]

Answer:

i think its x= 0.75

Step-by-step explanation:

substitute:

8x × 5 = 40x

8x × 10 = 80x

8 × 5 = 40

5 × 10 =50

40x + 80x = 40 + 50

add like terms

so it'd be:

120x = 90

now divide 90 by 120 and that would give you the value of x alone which is 0.75

What is the slope of the line that passes through the points (4, -9) and (-10, 18)?
Romashka [77]
-27/14


The formula is y2-y1 over x2-x1. If you plug in you points that would be 18-(-9) over -10-4. Subtract and that’ll be your answer. Hope this helps!
