Question

Two angles of a quadrilateral are 70 degree and 40° respectively and the remaining two angles are in the ratio 2:3 Find the measure of each angle of the quadrilateral

Answer 1

Answer:

Remaining angles = 100°, 150°

Step-by-step explanation:

40° + 70° + 2x + 3x = 360°

⇒ 5x = 250°

⇒ x = 50°

2x, 3x = 100°, 150°

Answer 2

Answer:

Two angles are 100⁰ and 150⁰

Step-by-step explanation:

$(70 + 40) + 2x + 3x = 360 \\ \: \: \: \: \: 110 + 5x = 360 \\ 5x = 360 - 110 = 250 \\ 5x = 250 \\ x = 50$
