Question

8. The measure of two angles of a triangle are 52° and 68°. Find the measure of third angle

​

Answer 1

Sum of all angles of triangle is 180°

let unknown angle be x
x+52+68=180
x=180-120
x=60°

Answer 2

GIVEN ⤵️

The measure of two angles of a triangle are 52° and 68°. Find the measure of third angle

Answer ⬇️

Sum of all angles in a triangle = 180°

( Angle sum property )

So, Let the third angle be x

52° + 68° + x = 180°

120° + x = 180°

x = 180° - 120°

x = 60°

$o, The third angle is 60°

PRØØF ✍️

52° + 68° + 60° = 180°

180° = 180°
