Question

Two adjacent angles are formed on a straight angle. If the angles are (7x+20) and 3x. Find the angles.​

Answer 1

TWO ADJACENT ANGLES FORMED ON A STRAIGHT LINE ARE LINEAR PAIR

(7x+20) + 3x=180

10x+20=180

10x=180-20

10x=160

x=160÷10

x=16

Angle 3x=16*3= 48

Angel(7x+20)= 7*16+20= 112+20=132

hence the angles are 48° and 132°

Answer 2

two Angles are 132 and 48

Step-by-step explanation:

Aa they are adjacent therefore

7x + 20 + 3x = 180

10x + 20 = 180

10x = 180 - 20

10x = 160

x = 160 ÷ 10

therefore x = 16

therefore two Angles are

1) 7x + 20

= 7(16) + 20

=112 + 20

= 132

2) 3x

= 3(16)

= 48

therefore two Angles are 132 and 48
