Question

the angles of a quadrilateral are in the ratio 3: 5: 9: 13 find the measure of its smallest angle​

Answer 1

Answer:

Solution. We have, ∠A : ∠B : ∠C :∠D = 3 : 5 : 9 : 13 . Hence, the smallest angle measures 36°.

Answer 2

Answer:

120°

Step-by-step explanation:

As we know that sum of all sides of a quadrilateral =360 °

so,

3x+5x+9x+13x=360°

30x=360°

so,x=360/30

the final answer is 12° so,the smallest angle=36 °
