Question

find the value of X

find the value of X given in the pic​

Answer 1

Answer:

80°

Step-by-step explanation:

In a triangle total angle is 180°

So,

45°+55°+x -180°

100°+x-180°

x-180°-100°

x-80°

Answer 2

Answer:

Sum of interior angles of a triangle is 180°

x + 55° + 45° = 180°

x + 100° = 180°

x = 180° - 100°

x = 80°
