Question

In a triangle, find the measure of angle O if angle N = 90 degrees, side MN = 20 cm and side ON= 32 cm. answer to nearest whole degree

Answer 1

if i have labeled the triangle correctly, you should see that tangent of angle 0 is 20/32
therefore \[O=tan^{-1}(\frac{20}{32})=32\]

Answer 2

yeah thats what i got

Answer 3

so its approximately 32 degrees?

Answer 4

?

Answer 5

yes that is what i got. it is the angle whose tangent is 20/32 if i labeled correctly, so it is the inverse tangent of 20/32 which my calculator told me was 32 degrees.

Answer 6

oh ok got it.
