Question

Two adjacent angles on a straight line are 'x' and (2x-21)then x ( )

Answer 1

Answer:

x = 67

Step-by-step explanation:

We know that

Sum of adjacent angles on a straight line = 180°

Hence, by the problem,

    (x) + (2x - 21) = 180

⇒ x + 2x - 21 = 180

⇒3x = 180 + 21 = 201

⇒x = 201÷3 = 67
