Question

In triangle ABC, angle C is a right triangle, what is the measure of x?

A. 42.1
B. 64.8
C. 23.1
D. 25.2

Answer 1

I'm sure you mean angle C is a right _angle_

Answer 2

You have the lengths of al 3 sides of the triangle, so you can choose which trig function to use to get the angle measure.

Answer 3

Keep in mind that for angle B,
28.3 is the adjacent leg
60.1 is the opposite leg
66.4 is the hypotenuse

Answer 4

ya that is what i meant sorry

Answer 5

Do you know the trig functions, sine, cosine and tangent?

Answer 6

no im stuck with what do to do now, lol

Answer 7

Have you ever learned SOH CAH TOA?

Answer 8

It's a way to memorize the trig functions in terms of the ratios they are equal to.

Answer 9

SOH means Sin = Opp/Hyp
CAH means Cos = Adj/Hyp
TOA means Tan = Opp/Adj

Answer 10

ok, thanks i completely forgot how to use sohcahtoa

Answer 11

Since you have all the lengths, you know what adj, opp and hyp are equal to.
You can use any of the three trig functions to get the angle.
sin x = 60.1/66.4
cos x = 28.3/66.4
tan x = 60.1/28.3

Answer 12

alright thanks!

Answer 13

sin x = opp/hyp
sin x = 60.1/66.4, etc.
