Answer 1

Answer:

sum of angles of triangle = 180°

x + x + x = 180°

3x = 180°

x = 180°/3

x = 60°

x + 2x + 90° = 180°

3x = 180° - 90°

3x = 90°

x = 90°/3

x = 30°

Answer 2

Answer:

1) Angle (x + x +x) = 180 (angle sum property)

3x = 180

x = 180/3

x = 60

So, in first Δ each angle is 60 degrees.

2) Angle (x + 2x + 90) = 180 ( A. S. P)

3x + 90 = 180

3x = 180 - 90

x = 90/3

x = 30

In second Δ

angle x = 30 degrees

angle 2x = 2 x 30

= 60 degrees
