Question

70 degree 90 degree 120 degree and 75 degree be the four angles of a quadrilateral ?why​

Answer 1

Answer:

Given, ∠A = 75°, ∠B = 90° and ∠C = 75°

We know that, sum of all the 1 angles of a quadrilateral is 360°.

∠A+ ∠B + ∠C + ∠D = 360°

⇒ 75° + 90°+ 75°+ ∠D = 360°

∠D = 360° – (75° + 90° + 75°)

= 360° -240° = 120°

Hence, the fourth angle of a quadrilateral is 120°.

Answer 2

Answer:

no because if we add 70,90,120 and 75 it is not equal to 360 and the sum of all angle should be equal to 360
