Question

Answers: A)116 degrees B)54 degrees C)62 degrees D)25 degrees

Answer 1

Answer:

The angle C is supplementary to the angle of 180°

180°-116°=64°

The sum of all sides of a triangle is always 180 °:

2x+4°+3x-13°+64°= 180°

5x+55°= 180°

5x=180°-55°

5x=125°

x=125°/5

x=25°

⇒A=3x-13°

A=3×25°-13°

A=75°-13°

A=62°

Answer C

hope this helps.
