Question

What is m a(3x+13)degrees b(x-8)degrees

Enter your answer in the box

Answer 1

(3x + 13) + (x - 8) + (x) = 180 --> x = 35

Answer 2

Answer: (3x+13)°= 118° and (x-8)°= 27°.

Explanation:

We know that , According to the angle sum property of triangle : the sum of all angles of a triangle is 180°.

According to the given picture , in triangle ABC , we have

∠A =(3x+13)° , ∠B = (x-8)° and ∠C=x°

Now , by angle sum property , we have

(3x+13)° + (x-8)° +x°= 180°

⇒ 3x+13+x-8+x=180

⇒ 5x+5=180

⇒ 5x=175 [subtracting both sides by 5]

⇒ x= 35 [Dividing both sides by 5]

Now , (3x+13)° =( 3(35)+13) ° =118°

(x-8)°= (35-8)° = 27°

Hence, the answer is (3x+13)°= 118° and (x-8)°= 27°.
