Solve for x in the diagram below.

Answer:
x = 40
Step-by-step explanation:
the line is 180 and there is already a target that is 100
so both x are 40
Answer:
x=40⁰
Step-by-step explanation:
Since a half a circle is 180⁰ and you already have 100⁰. Subtract 180⁰-100⁰ which gives you 80⁰ now divide that by 2 because you are looking for 2 x's which your answer is x=40⁰
