1. The measure of the side is 40.0
2. The measure of the side is 36.3
3. The measure of the angle is 49.8
4. The measure of the side is 41.4
How to find the required part
1. To find x we use trigonometry
tan 72 = x / 13
x = tan 72 * 13
x = 40.0
2. tan 15.4 = 10 / x
x = 10 / tan 15.4
x = 36.3
3. tan x = 13/11
x = arctan (13/11)
x = 49.8
4. cos x = 3/4
x = arcos (3/4)
x = 41.4
