Question

plz solve 5 sum........​

Answer 1

Answer:

Ratio of two angles is 2:3

let 2:3 be 2x and 3x

Sum of all the angles of quadrilateral is 360

= 2x + 3x + 70 + 40 = 360

5x + 110 = 360

5x = 360 - 110

5x = 250

x = 50

hence x is 50

now 2x, 2×50 = 100

and 3x, 3×50 = 150

hence another two angles are 100 and 150 degree.

Verification-

sum of all the angles of quadrilateral = 360

70 + 40 + 100 + 150 = 360

360 = 360

Hence prove
