Hey there,Lets solve this problem together.
We know that the hypotenuse of a right triangle is 50 millimeters long. One leg of the right triangle is 30 millimeters long.
Hypotenuse = c²
= 50
α² = 30
-------------- Calculations
\(\alpha^2 + \beta^2 = c^2\)
\(30^2 + \beta ^2 = c^2\)
\(\beta ^2 = c^2(50) - a^2(30)\)
\(cb = \sqrt{1600}\)
\(C = 40\)
