Question

find the value of x in each of the following figure​

Answer 1

Answer:

x =80°

Step-by-step explanation:

angle of triangle = 180°

angle A + angle B + angle C = 180°

x + 55° + 45° = 180°

x + 100° = 180°

x = 180° - 100°

x = 80°

Answer 2

Answer:

35°

Step-by-step explanation:

sum of the angles of a triangle = 180°

55°+90°+x = 180°

145°+x = 180°

x = 180°-145° = 35°
