I came up with this when I was throwing a Frisbee with my friends.
See if you can solve it.
This is how my Dad and I solved it:
We had to break it into 2 right triangles with the same height C.
Then we found C’s value using the Pythagorean Theorem and some algebra.
Then we used the sine inverse on the calculator to find 2 angles (19.41 and 66.o3).
This works because the sine of an angle in a right triangle = the opposite side divided by the hypotenuse.
Finally we used our knowledge that all angles on a triangle add up to 180 degrees to find the last angle (94.56).
