Angle RST and Angle GSH are vertical angles. Angle RST = 5b + 20 and Angle GSH = 7b - 4. What is the measure of Angle RST?
.

The measure of angle RST is 80

Step-by-step explanation:

Since they are vertical angles, then they must be equal as vertically opposite angles are equal

Thus;

5b + 20 = 7b - 4

7b - 5b = 20 + 4

2b = 24

b = 24/2

b = 12

But RST = 5b + 20

substitute for b

RST = 5(12) + 20

RST = 60 + 20

RST = 80

step-by-step explanation:

u take $30 minus $24. the answer/original($30)

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply
