Triangle
Area = 1/2 b * h
Area = 1/2*15 * 9 = 1/2 * 135 = 67.5
Rectangle
Area = b * h
Area = 15 * 4
Area = 60
Trapezoid
Area = (1/2) * (b1 + b2)* h
Area = (1/2) * (15 + 18) * 4
Area = 1/2 * 33 * 4
Area = 66
Total Area
Total Area = 66 + 60 + 67.5 = 193.5 Answer
Answer:
for 1 it is the 3rd graph
Step-by-step explanation:
Using the cosine function:

Solve for b:
Hi Student!
This question is fairly simple because it gives us an equation and they also give us a value for the variable that is within the equation and they tell us evaluate the expression. So let's plug in the values and solve.
<u>Plug in the values</u>
<u>Factor out the exponent</u>
<u>Combine</u>
Therefore, the final answer that we would get when substituting m with 9 in the given equation is that we get 86.
