Question

In triangle GHI, angle H is a right angle, GH = 40, and cos G= 40/41. Draw a diagram and find each value in fraction and in decimal form.
a) Sin G
b. Sin I
c. Cot G
d. csc G
e. cos I
f. sec H
- I have no idea how to do this

Answer 1

the triangle's 3rd side is √(41^2-40^2) = 9

So, now you know all three sides, and the angles, so the trig functions are easy to read off.

sin G = 9/41
and so on
