40 points for this and thanks for helping

B hopefully this helps you with work

Given:

∠C = 80°

∠A = x°

∠B = 3x°

To find:

A) Value of 'x'

B) Measurement of angle A and angle B

Steps:

A) We know that the sum of angles of a triangle is equal to 180°

So,

∠A + ∠B + ∠C = 180°

    x + 3x + 80 = 180

  4x + 80 - 80 = 180 - 80          (subtracting 80 from both sides)

                  4x = 100

               4x/4 = 100/4               (dividing both sides by 4)

                     x = 25°

Therefore the value of x is 25

B) Since we know the value of x, we can find the measurements of angle A and B

∠A = x

∠A = 25°

∠B = 3x

∠B = 3 × 25

∠B = 75°

Therefore the measurements of angle A is 25° and measurement of angle B is 75°

Happy to help :)
