Answer:
Add the area of the rectangle with the semicircle.
10x4 + 0.5(3.14)(25)
40+39.25
79.25
So the answer is C. 79.
Let me know if this helps!
Answer:
Step-by-step explanation:
Since two sides of the triangle are equal in length, we can conclude that 
is an isosceles triangle. With this information, we can draw an isosceles triangle to find 
. Since the base angles of an isosceles triangle are equal, we can solve for :
(Angle sum of triangle is 
)
(Base angles of isosceles triangles are equal, there is an image attached to show that is one of the base angles)
Hope this helps :)

When we are given 3 sides, we try to solve the angles first by using the
law of cosines
cos (A) = [b^2 + c^2 - a^2] / (2 * b * c)
cos (A) = [43^2 + 17^2 -27^2] / (2 * 43 * 17)
cos (A) = [1,849 + 289 -729] /

</span></span></span>cos (A) = 1,409 / 1,462
cos (A) =

0.96374829001368
Angle A = 15.475
Now that we have one angle, we next can use the
Law of Sines
sin(B) / side b = sin(A) / side a
sin(B) = sin(A) * sideb / sidea
</span></span></span><span>sin(B) = sin(15.475) * 43 / 27
</span><span>sin(B) = 0.26682 * 43 / 27
sin (B) = </span><span>0.424935555555</span>
Angle B = 25.147 Degrees
Remember the arc sine (<span>0.424935555555) also equals </span>
<span>
<span>
<span>
154.85
</span></span></span>Finally, calculating the third angle is quite easy
Angle C = 180 - Angle (A) - Angle(B)
Angle C = 180 - 15.475 - 154.85
Angle C = 9.675
