Question

The angle of elevation is 27 degrees. The a side of the triangle is 15,000. The b side of the triangle is 13,365. How do you find the missing angle, and the hypotenuse? I really need help with this

Answer 1

If its 27 deg... the base is 15k and side is 13,365. This isnt geometry this will need some trigonometry :)
See now you know that hypotenuse is base^2 + perpendicular^2 whole root. So you will have 20090.3764 for the hypotenuse. You know all three sides now, one of the angles is 90 deg and one is 27. Now you can either use trig or basic triangle sum rule. all angles of triangle add upto 180. So 180 = 90 + 27 + x
thus the other angle = 63 deg :)

Answer 2

This is only assuming its a right angled triangle cause you siad hypotenuse. Otherwise youre getting yourself into some deep cosine/sine rule pellet ;)
