Answer:
Step-by-step explanation:
Given that the left angle =
The right angle across from it
The other two angles are x and x.
We know that the sum of angles at a point equals 360 degrees.

The value of x is approximately 38.5 degrees.
Hello!
First of all, let's find the triangle. As we can see, it is eight units long and four units tall. We can use the triangle formula and half the product.
4(8)=32
32/2=16
Now we need to find the area of the semicircle. We can use circle formulas and half our final answer. We will find the area using A=r².
We know that the diameter of this circle is eight. Therefore our radius is 4.
A=²
A=
Now we multiply.
16≈50.27
Now we add our triangle.
50.27+16=66.27
The nearest answer to this is B)66.2. It may have been a bit over as we used , not 3.14.
I hope this helps!
