Question

In quadrilateral ABCD, angle A is 72, angle B is 94, and angle C is 113. What is angle D

Answer 1

Answer:

SUM OF ALL ANGLES OF TRIANGLE = 360

LET THE REMAINING ANGLE BE X

72 + 94 + 113 + X = 360

299 + X = 360

X = 61

REMAINING ANGLE = 61

hope it helps.....

Answer 2

$\Large\underline{\underline{\orange{\bf{\:Question}}}}$

In quadrilateral ABCD, angle A is 72, angle B is 94, and angle C is 113. What is angle D

$\Large\underline{\underline{\orange{\bf{\:SolutioN}}}}$

$\large\underline{\sf{\:Given}}$

• Angle of quadrilateral ABCD are, <A = 72°, <B = 94° , <C = 113° .

$\large\underline{\sf{\:Find}}$

• Angle of D.

$\Large\underline{\underline{\orange{\bf{\:Explanation}}}}$

We Know,

★ All angle of any Quadrilateral always will be 360° .

So, Here

• <A + <B + <C + <D = 360°

$\mapsto\sf{\:72 + 94 + 113 + D=360}$

$\mapsto\sf{\:D\:=\:360-279}$

$\mapsto\pink{\sf{\:D\:=\:81°}}$

$\LARGE\red{\underbrace{Thus}}$

★ Angle of D will be = 81°
