Need to find the number for a
Shalnov [3]
Answer to the first triangle: 15

To solve this we will use the Pythagorean theorem

Pythagorean theorem formula: a^{2} +  b^{2} =c^{2}

Lets do the first triangle. 

17 is the hypotenuse, so its going to replace c in the formula.

8 is the height and it is going to replace a in the formula.

a is what we are trying to find, so our b in the equation is going to be the unknown.

8^2 + b^2 = 17^2

64 + b^2 = 289



b^2 = 289 - 64

b^2 = 225

\sqrt{b^2}  =  \sqrt{225}

b = 15

now we know that the missing length in the first triangle (a) is 15

Can you solve the Other one?

Just comment if you need help on the other one.
