Step-by-step explanation:
8x = 1
x = 1/8
So x = 1/8 is the correct answer
<span>Use a proportion:
x/(5 1/2) = 50/4
--------
x = (11/2)(50/4)
--------
x = 550/8
----
x = $68.75</span>
The answer is B because C and D are not true. Angle-Angle theorem does not prove congruency. Hypotenuse-Leg does because having a hypotenuse means that the triangle is a right angle triangle, which means that 2 sides and an angle are congruent in the triangles. By Side-Side-Angle Theorem, the triangles are congruent.
Find the area of the circle using A=pi * r^2 and then divide that answer by 2 and that will get you the area of the semicircle.
