Answer:
x = 24.2
y = 12.1
Step-by-step explanation:
The side with length x, the side with length 21, and the angle of 60° are related by the trigonometric function sine, so:
Therefore, solving for x, we get:
Then, sin 60 = 0.86, so the value of x is:
In the same way, the value of y is related by the trigonometric function tangent as:
So, solving for y, we get:
Since tan 60 = 1.73, we get:
Therefore, the answers are:
x = 24.2
y = 12.1
