Question

In quadrilateral abcd, if angle a=60° and angle b:angle c:angle d = 2:3:7, then find the value of angle d​

Answer 1

Answer

angle b= 50, angle c=75, angel d=175. hope it may help you

Answer 2

Given :

• Angle a = 60°
• Angle b = 2x
• Angle c = 3x
• Angle d = 7x

Sum of Angle in quadrilateral = 360°

$\bf 60 + 2x + 3x + 7x = 360 \\ \\ \bf12x = 300 \\ \\ \large \underline{\boxed{ \bf \orange {x = 25}}}$

$\boxed{ \bf \angle a = 60°} \\ \\ \boxed{ \bf \angle b = 50°} \\ \\\boxed{ \bf \angle c =75° } \\ \\\boxed{ \bf\angle d = 175°}$
