Question

9. What is the value of x in the
figure shown?
104°
38°
​

Answer 1

x = 66

Explanation:

So the angle with 104 that's the outside measure of the angle but we need to find the inside measure so first.

180 -104= 76 (so 76 is the measure to the inside angle)

Now

76 + 38 + x = 180 (collect like terms)

114 + x = 180 (minus 114 on both sides)

x = 66
