Step by step solution:

$we \ know \ that\\\\a+b=180\\\\putting \ value \ here\\\\2x+10+20+3x=180\\\\5x+30=180\\\\5x=150\\\\x=30$

Hope it is clear to you.

Answer 2

Step-by-step explanation:

we know that sum of adjacent angles of a triangle is 180°

therefore; angle a +angle b =180°

(2x+10)+(20+3x)=180°

5x+30=180°

5x=180-30

5x=150°

x=150÷5

x=30°
