Question

the ratio between the angles of a quadrilateral is 7:2:5:6 respectively. what is the sum of double the smallest angle and half of the longest angle of the quadrilateral?

Answer 1

$= > 7x + 2x + 5x + 6x = {360}^{0}$

$= > 20x = {360}^{0}$

$= > x = \frac{360}{20} = 18$

$Therefore,Required \: answer =$

$\frac{15x}{2} = \frac{15 \times 18}{2} = {135}^{0}$

I hope this will help you dear..
