Answer: 28.8°
<u>Step-by-step explanation:</u>
∠A = 5(∠B) + 7.2°
∠B = ∠B
Since they are on a straight line, they form a linear pair (sum = 180°)
∠A + ∠B = 180°
Use Substitution:
5(∠B) + 7.2° + ∠B = 180°
Add like terms:
6(∠B) + 7.2° = 180°
Subtract 7.2° from both sides:
6(∠B) = 172.8°
Divide both sides by 6:
∠B = 28.8°

I dont think so because an acute angle is always lower than 90 so .. i dnt think even two will add up more than 90
Answer:
I think the answer is 3 ( Maybe)
Answer:
m=-1/5
Step-by-step explanation:
Slope formula which you will need is (y2-y1)/(x2-x1)
The two y values are 3 and 1
The corresponding x values are -9 and -1
(3-1)/(-9-1)
2/(-10)
Simplify
-1/5
