Explanation on how to solve these problems (not answers to the problems).

..

Step-by-step explanation:

First, you need to make sure that you know a few things.

1. A line is 180 degrees

2. Angles with the small boxes on them are right angles.

3. Angles that are across from each other are the same amount of degrees...

For example, look at angle 2, you can see that directly across from it is the angle 35 degrees, this makes angle 2 35 degrees as well.

In order to find angle 1, you need to subtract 35 from 180, to see how much is needed to fill the line, in this case it is 145.

So, angle 1 is 145 degrees, and angle two is 35.

One more thing, angles 1 and 7 are the same and so are 2 and 6 because they are on the same line, I can't remember why, but they are.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
