Answer:
B
Step-by-step explanation:
∠ 4 and ∠ 5 are alternate interior angles and are congruent, thus
∠ 5 = 95° → B
Given:
Right triangle
θ = 60°
To find:
sin 60°
Solution:
The reference image is attached below.
The given triangle is a right triangle.
θ = 60°
Using basic trigonometric ratio formula:
The value of sin 60° = .
In the given figure, the values of adjacent side, opposite side and hypotenuse are not given.
For the first part, the results get quite crazy. I hardly believe that you're supposed to do this by hand, so I'm afraid that there's some typo in the question.
As for the second part, we have
Plug your value for x and you have
We can rewrite the quantity as
