Question

One angle of a quadrilateral is 150°and other three angles are equal. What is

the measure of each of these equal angles ?​

Answer 1

Answer:

⇒ The sum of first angle second angle =150

⇒ The ratio of third and fourth angle is 2:3

⇒ Let third angle fourth angle be 2x and 3x.

We know that in quadrilateral sum of four angles is 360

∴ 150

+2x+3x=360

⇒ 5x=210

⇒ x=42

⇒ Now,

2x=2×42

=84

⇒ 3x=3×42

=126

⇒ The measure of two angles are 84 and 126
