Answer:

65 degrees

Step-by-step explanation:

Since complementary angles are 2 angles that add up to 90 degrees, all you have to do is subtract 25 from 90.

When you do that you get 65.

Example: 90 - 25 = 65

Find the indicated side of the<br> right triangle.

Advocard [28]

Answer:

?=9

Step-by-step explanation:

We have a special right triangle, the 45-45-90 triangle.

In a 45-45-90 triangle, the side lengths are x, and the hypotenuse is x√2.

Since we know that the side length is 9, this means that:

$x=9\\\text{Hypotenuse}=x\sqrt2\\\text{Hypotenuse}=9\sqrt2$

The ? is 9.
