Question

Help please I’ll mark you

Answer 1

X = 23

Explanation:

Think of it like this:

BC is a right angle so it sums up to 90°

So: 67+90 is 157

A diameter cuts a circle in halves and each half is equal to 180° because a full circle is 360°.

So: 180-157 = x

23 = x

I hope this answers your question :)

Answer 2

23

Explanation:

x + 90 + 67 = 180 {Straight line angles}

x + 157 = 180

x = 180 - 157

x = 23
