Question

Help me pls!! Thank you!

Answer 1

angles opposite by the vertex therefore equal

we put the equation

8z-3=7z+7

we solve

8z-7z=7+3

z= 10°

we calculate the measure of the angles:

8z-3=8*10-3=77°

7z+7 = 7*10 + 7 =77°

each angle has a measure of 77°

Explanation:

Answer 2

Answer: Z = 10

Explanation:

8z-3 = 7z+7

z-3 = 7

z = 10
