Question

Find the value of the unknown interior angle x in the following figures:
​

Answer 1

$\huge\underline\mathrm{SOLUTION:-}$

We Know That,

An exterior angle of a triangle is equal to the sum of its interior opposite angles.

x + 50°

= 115°

By transposing 50° from LHS to RHS it becomes - 50°

x = 115o - 50°

x = 65°

• Hence, x = 65°.
