Question

If two supplementary angles are (7x - 5) and (3x + 25), then evaluate the measure of the angles.​

Answer 1

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 2

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˚
