Question

the sum of the two angles of a quadrilateral is 145° . the other two angles are in the ratio 2:3 . find the angles

Answer 1

Answer: 86° and 129°

Step-by-step explanation:

The sum of the angles for each quadrilateral is 360°.

360°-145°=215°

2x+3x=215

5x=215

x=43°

2x=2×43=86°

3x=3×43=129°

Answer 2

∠$C=3x=129$

∠$D=2x=86$
