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.
A For the first one and c for second one
28/21=42/x multiply both sides by x
28/21x=42 divide by 28/21 on both sides ( or multiply both sides by 21/28)
X= 63/2
X= 31 1/2
Answer:
6x. The coefficient is 6.
