Question

PLZ HELP its Triangle Properties and where using the 45º-45º-90º Triangle Theorem and the 30º-60º-90º Triangle Theorem.

Answer 1

Triangle ABC is an isosceles right triangle. What is the measure of one base angle?

45º

Explanation:

Answer 2

The answer to your questions is below

Explanation:

4.-

In a 45°-45°-90° triangle, the length of the legs are "x" and the length of the hypotenuse is x
`√(2)`

Then, in this problem, the length of the leg is 7 then the length of the hypotenuse will be 7
`√(2)`

5.- In a 30°-60°-90° triangle, the length of the hypotenuse is 2x, the length of the longer leg is x
`√(3)` and the length of the shorter leg is x.

In this problem we have the length of the hypotenuse = 20 and find x.

2x = 20

x = 20/2

x = 10

longer leg = x
`x√(3) =<strong> 10√(3)`

6.- nonzero

7.- hypotenuse = 20 cm

Find x

2x = 20

x = 20/2

x = 10

Shoter leg = x = 10 cm
