(I would really appreciate the help I know a 100 points are a lot so please don't answer for points lol and ty) (giving brainliest and rating and thanks if right!) Mr. Morris is going to save money and replace his sailboat's mainsail himself. He must determine the area of the mainsail in order to buy the correct amount of material. Calculate the area of the parallelogram to determine how much material should be purchased. Be sure to explain how to decompose this shape into rectangles and triangles. Describe their dimensions and show your work. Parallelogram with base of 14 feet, height of 12 feet, and triangle base of 3 feet.

Welllfrom the diagram, you can see you have two triangles (one on each side)

area of triangle = 1/2 base*height = 1/2 * 2 x 10 = 10 ft2 each

then you are left with a rectangle 13 ft x 10 ft = 130 ft^2

130 + 10 + 10 = 150 ft2

or you could just use the formula for area of parallelogram base * height = 15 * 10 = 150 square feet

Can I get a brainliest plsss

-6 is the correct option from the above given options

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
