Hehe, these are fun to do. There are two ways to do this kind of problem. You can use the pythagorean theorem or we can use the distance formula.
Distance formula:
Pythagorean Theorem:

Distance formula is better if you're finding distance between two
coordinates. The Pythagorean Theorem only really works for independent values. If I had 2 sides of a triangle, and I needed to find the third, I'd use this equation to find it. In this case, we'll use the distance formula.
I'll work the first one out for you:
x1 y1 x2 y2
(3, 2) & (7, 4)
v

There's your answer!

Answer:
C
Step-by-step explanation:
sum of angles in tri are 180
180-35-36=109
10(4^2-(9)
Since 16-9 is 7
And 10 times 7 is 70
Answer:
4.1 inches
