Question

I need to know how to do this lol​

Answer 1

here, 76 + 2x = 122.
So x = (122-76)/2=23

Answer 2

Your answer would come to x = 23

If we know that the whole angle subtended equals 122°, then to find the value of x we need to find what's left over when we subtract 76°, and then divide this by 2.

This gives us:

122 - 76 = 46

46 ÷ 2 = 23

Therefore your answer is x = 23

I hope this helps!
