Answer:84 and 86

Step-by-step explanation:

Suppliment angles form 180°

So,7x+8x=180°

15x = 180°

x=12°

Now, 7x = 7×12 = 84

Similarly 8x = 8×12=96

There you go!!!

Answer:

84degrees,96degrees

Step-by-step explanation:

two angles =7x,8x

7x+8x=180

15x=180

x=12degrees

angles=7x=7(12)=84degrees

8x=8(12)=96degrees
