we know that
The measurement of the exterior angle is the semi-difference of the arcs which comprises
In this problem
∠FGH is the exterior angle
∠FGH=
∠FGH=
-----> equation A

--------> equation B
Substitute equation B in equation A
![100\°=(arc\ FEH-[360\°-arc\ FEH])](https://tex.z-dn.net/?f=100%5C%C2%B0%3D%28arc%5C%20FEH-%5B360%5C%C2%B0-arc%5C%20FEH%5D%29)



therefore
<u>The answer is</u>
The measure of arc FEH is equal to 
Answer:
if it is multiple choice:
x=2
x=3
Step-by-step explanation:
Solution:
<u>We know that:</u>

<em>Since we are already given the base and the height, we can substitute them into the formula to find the area of the triangle.</em>

<u>Cancel out the "2" by dividing it by 18.</u>

<u>Simplify the multiplication.</u>

Answer:
Step-by-step explanation:
A is a subset of B while B is the universal set.
AB = A U B
A is a subset of B. That is A is contained in B.
<h2>B is the correct answer!</h2><h3>(There's a chance I might be wrong.)</h3><h3></h3><h3>You have to rotate the shape by 180 degrees to get the other shape. (Sorry, I'm not good at explaining.)</h3><h3></h3><h3><em>Please let me know if I am wrong.</em></h3>
