Question

What is the area of ABC below? If necessary, round your answer to two decimal places.

Answer 1

First find AD and DC using pythagors theorem. Later use the formula for triangle área:
Area = base x height

Answer 2

i dont have a base

Answer 3

You can calculate the base of each separate triangle using the Pythagorean theorem. The triangle on the left would be equal to
(7.9)^2+x^2=(9.4)^2

The larger triangle would be equal to (7.9)^2+x^2=(23.2)^2

Just solve both equations for x, and you have the length of the base of each triangle. Add them together, and you have the length of the larger triangle.

Answer 4

this is what i got after separating them 91.64 and 34.13

Answer 5

I'll show you some steps.
Any polygon can be divided into right triangles. This particular triangle can be looked at as the product of two separate triangles. Using the Pythagorean theorem, you can solve each triangle separately.

Just remember, that the Pythagorean theorem is base^2+height^2=hypotenuse^2.
