TO FIND

x

___________________________

We know that,

Sum of all interior angles of a triangle is 180°

Let's take

50° = A , 72° = B , 45° = C

( A + x ) + B + C = 180° ( Interior Angles of A Triangle )

( A + x ) + 72° + 45° = 180°

( A + x ) + 117° = 180°

A + x = 180 - 117

A + x = 63

A + x = 63°

___________________________

We know that,

A = 50°

A + x = 63°

50° + x = 63°

x = 63 - 50

x = 13

x = 13°
