pls help it's urgent
​

Answer 1

Answer:

115 degrees

Step-by-step explanation:

Since △ABC is isosceles, / B=/ C

A+B+C=180

50+2B=180

2B=130

B=65

x=A+B (Exterior angle property)

x=50+65

=115 degrees

Answer 2

Answer:

x = 115°

Step-by-step explanation:

In triangle ABC angle A = 50°

A+B+C = 180°

angle B and angle C must be same because angles opposite to the equal sides are equal

B+C = 130°

B+B = 130°

2B = 130°

B = 65°

angle C is also 65°

C+x = 180°

x = 180°- C

x = 180° - 65°

x = 115°
