Answer:
7x-5 = 107°
3x+25 = 73°
Step-by-step explanation:
(7x-5)+(3x+25)=180° (angles are supplementary)
⇒ 10x + 20° =180°
⇒10x = 180-20
=160°
⇒ x = 160/10
= 16°
⇒ 7x-5 = 7(16) - 5 = 112-5 = 107°
and 3x +25 = 3(16) + 25 =48 +25 = 73°

Answer:
107˚ and 73˚
Step-by-step explanation:
Sum of supplementary angles is 180˚
(7x-5)+(3x+25)=180
10x+20=180
x+2=18
x+16
First angle=7x-5
=16(7)-5
=107˚
Other angle=180˚-107˚
=73˚
