(asap worth 10 points) marcus loves baseball and wants to create a home plate for his house. marcus needs to calculate the area of the home plate at the ball field so he can reconstruct it when he gets home. calculate the area of the polygon.
72.5 in
75.5 in
83 in
96 in

83 in²

Step-by-step explanation:

To calculate, add the areas of all three shapes that make up the polygon.

Area of rectangle = L×W = 5×8 = 40 in².

Area of top triangle = 1/2×b×h = 1/2×8×7=28 in².

Area of triangle on the right = 1/2×6×5 = 15 in².

Total area = 40+28+15 = 83 in²

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
