Question

find the value of x ​

Answer 1

Answer:

Angle B = 180 - 110 = 70

Angle C = 180 - 120 = 60

Sum of angles in a triangle is 180, so the other angle is 180 - ( 70 + 60 ) = 50

so, x = 180 - 150 = 30 degrees

Answer 2

Answer:

x = 180 - 150 = 30°

Step-by-step explanation:

Angle B = 180 - 110 = 70

Angle C = 180 - 120 = 60

Sum of angles in a triangle is 180, so the other angle is 180 - ( 70 + 60 ) = 50

so, x = 180 - 150 = 30°
