00:04
So solve the remaining for the remaining sides and angles if possible, if not or answer d and e in all answer boxes.
00:15
So the size given are side a is 16, side b is 12, side c is 20.
00:25
Since we know that, and if you look at these numbers, 16, 12, and 20, if you divide them all by 4, 4, that becomes 3, and that becomes 5, which means this is a right triangle.
00:44
One side is three, one side is four, and one side is five.
00:49
So the three, four, five right triangle.
00:54
So then to figure out any of the angle, so then we know that in our right triangle, 20 is our hypotenuse because it's the longest side, and one side is 12, or the other one is 16.
01:07
And since 20 is one of the sides, and it's the hypotenuse, this is our right angle.
01:13
So that angle right there is 90 degrees.
01:17
So angle c is 90 degrees...
