Find the area of the figure.

11.5 ft²

Step-by-step explanation:

Since it's a composite figure, you need to find the areas of the separate shapes first.

Rectangle

(4)(2.5) = 10

Triangle

1/2(1.5)(2)

1/2 (3)

1.5

Now add them together -- 10 + 1.5 = 11.5 ft²

so what is the problem what are they asking you to solve

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.
