Help please I’ll mark you

23

Step-by-step explanation:

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

x + 157 = 180

         x = 180 - 157

         x = 23

X = 23

Step-by-step 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 :)

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
