Question

A quadrilateral has three angles equal to 65 degree. Find fourth angle

Answer 1

Hey mate ☺️

Let Ist angle = A

IInd angle = B

IIIrd angle = C

IVth angle = D

According to the Question...

Given :

A + B + C = 65°

To Find :

D = ?

Solution :

A + B + C + D = 180°

65° + D = 180°

D = 180° - 65°

D = 115°

I Hope it helps you ☺️ ✌️ ✌️

Answer 2

Step-by-step explanation:

Let the fourth angle be x.

Given three angles = 65°,65°, 65°

Sum of angles of a quadrilateral = 360°

65°+65°+65°+x = 360°

195° + x = 360°

x = 360° - 195°

x = 165°
