Since this is a right triangle, we can use one of the three main trigonometric functions: sine, cosine, or tangent.
Remember: SOH-CAH-TOA
Looking from angle I, we know the opposite side and the hypotenuse. Therefore, we should use sine.
sin(I) =
To solve, you can use your calculator and the inverse sine function (sin^-1).
I = sin^-1()
I = 61 degrees
Hope this helps!
So for this, multiply both sides by 9, and your answer will be:
Answer:
Option c
Step-by-step explanation:
We assume that the angle is in the first quadrant.
Observe the attached image.
if
So:
By definition:
So:
adjacent side = 3
hypotenuse = 5.
Observe the attached image
We find the opposite side "x" using the Pythagorean theorem.
Then, for the angle u:
