Question

two vertically opposite angle measure (x+90°) and (2x+60°). find the angles​

Answer 1

Answer:

X=30 DEGREES

AS VERTICALLY OPPOSITE ANGLE ARE EQUAL

SO

X+90=2X+60

90-60=2X-X

X=30

Answer 2

As we know vertically opposite angles are equal so,

(x +90) = (2x + 60)

x + 90 = 2x +60

90-60 = 2x - x

30 = x

so,

measure of the angles are

( x +90 ) = 30 + 90

= 120

( 2x + 60) = 2 × 30 + 60

= 60 + 60

= 120

both angles are equal because they are vertically opposite angles
