498.12

Step-by-step explanation:

To find the answer you need to first find the area of the triangle which is simply where b is the base and h is the height when you plug the numbers in you get 96 for the area and to find the area of the semicircle you have to use the formula and you would get 128 pi which is 402.12 and when you add the numbers you get 498.12 as the area

x= 149. 24+7=31. 180-31=149

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
