Answer 2

Hello mate..

Here Is Your Answer:

Given:

∠A = 60°

∠B = x

∠C = y

To find:

∠B = x

Solution:

$\bold{sum \: of \: all \: angles \: in \: a \: triangle \: = 180°}$

$\bold{straight \: angle = 180°}$

$Linear \: pair \: of \: 120° = 180 - 120 \\ y= 60°$

Logically, If two angles in a triangle are 60° then the third angle also will be 60° and named as equilateral triangle. Here x = 60°

∠B(x) = ∠A + ∠C - 180°

x = 60 + 60 - 180

x = 120 - 180

x = 60°

HOPE THIS HELPS YOU..
