Use the Pythagorean theorem to find the hypotenuse of a triangle with two legs measuring 3 inches and 4 inches.
The hypotenuse is 5 inches
a2 + b2 = c2 or L2 + L2 = H2
32 + 42 = c2
9 + 16 = c2
25 = c2
Take the square root of each side to get 5 = c

Find the missing side of two proportional of triangles:
Triangle 1: Side A = ?; Side B = 15
Triangle 2: Side A = 6; Side B = 5.
Set up the proportions and solve. What does A =?
A = 18
A/6 = 15/5
Cross multiply:
5A = 15 x 6
5A = 90
A = 90/5
A = 18
