Question

If the angles 3x and 2x + 30 are
linear pair, then find the value of 'x'.​

Answer 1

Answer:

3x+2x+30=180

5x+30=180

5x=180-30

5x=150

x=150/5

x=30

Answer 2

Answer:

I hope it helps

Step-by-step explanation:

As we know that sum of the measure of an angle and its complement is equal to 90° (3x – 20)° + (2x – 40)° = 90° ⇒ 5x – 60° = 90° ⇒ 5x = 150° ⇒ x = 30°
