Question

Solve the following questions. 1) Find the value of x in the following figure. х 90 130.​

Answer 1

Step-by-step explanation:

Let the given triangle be ABC.

$\rm130° + C = 180° (linear \: pair)$

$\rm C = 180° - 130°$

$\rm C =50°$

Since the sum of the three angles of a triangle = 180°

$\rm \angle{A }+ \angle{B }+ \angle{C }= 180°$

$\rm x + 90° + 50° = 180°$

$\rm x + 140° = 180°$

$\rm x = 180° - 140°$

$\rm x = 40°$
