Answer:

A. 7 centimetres and 25 centimetres

Step-by-step explanation:

To see if the lengths make a triangle, use the Pythagorean theorem. Insert the biggest value as c (the hypotenuse, which is always the longest side in a right triangle). If both sides equal each other, it is a right triangle:

a^2+b^2=c^2

A.

24^2+7^2=25^2\\\\576+49=625\\\\625=625

This is a right triangle.

B.

23^2+8^2=24^2\\\\529+64=576\\\\593\neq 576

Not a right triangle.

C.

9^2+22^2=24^2\\\\81+484=576\\\\565\neq 576

Not a right triangle.

D.

24^2+10^2=27^2\\\\576+100=729\\\\676\neq 729

Not a right triangle.

Done :D

A ladder leans against the side of a house. The angle of elevation of the ladder is 67 degrees when the bottom of the ladder is
Lynna [10]

Answer:

32.98 ft

Step-by-step explanation:

What you have right there is a triangle.

The base of the triangle is given (14 ft)

The angle from the ladder makes while leaning on the house is 67 degrees.

This is a simple trigonometry problem

You want to find the length of the ladder and you don't have the hypotenuse

So you can use the function tan to find it.

tan(Ф) = opposite/adjacent

You are looking for the opposite side length

So you do tan(Ф) * adjacent = opposite

tan(67) * 14 = 32.98 ft
