Answer :

the sum of all angles of a quadrilateral is 360 degree
let the other  angle bex
so , 80 +135 + x+x=360
215+2x=360
2x=360-215
2x=145
x=72.5
other two angles is 72.5

Dear Student,

◆ Answer -

72.5°

● Explanation -

Let x be measure of other two angles of quadrilateral.

As we know, sum of 4 angles of quadrilateral is 360°.

80° + 135° + x + x = 360°

215° + 2x = 360°

2x = 360° - 215°

2x = 145°

x = 145/2

x = 72.5°

Hence, measure of other two angles will be same. i.e. 72.5°.

Thanks dear. Hope this helps you...
