Question

What is the value of x in the triangle?

Answer 1

D=5√3

Explanation:

since 15 is the leg opposite to the 60 degrees angle, you can say:

(√3)/2(hypotenuse)=15

Then if you solve, you find the hypotenuse to be √300

Next, since side x is opposite to a 30-degree angle, it will be half the hypotenuse which will be:

√300/2 OR 5√3

Answer 2

5√3

Explanation:

use the function tangent which is opposite over adjacent and from the 60 degrees angle's prespective x is the adjacent and 15 is the opposite so its tan(60)=15/x

x=15/tan(60)

x=5√3
