Question

Annie made a platform for a stage. The platform has to be in the shape of a right triangle so that it fits in the center of the rectangular stage. In the picture shown below, the rectangle shape represents the stage and the shaded triangle represents the platform.

Answer 1

She said the length of the platform should be greater than 25 inches. Is Annie correct?

Answer 2

Do you know the pythagorean theorem?

Answer 3

yeah, a^2+b^2=c^2

Answer 4

in this case, a = 45, b = x and c = 51

so

a^2 + b^2 = c^2

45^2 + x^2 = 51^2

Solve for x to find the length of b (the missing side length of the triangle)

Answer 5

Does B=24?

Answer 6

yes it does
