Question

What is the value of x?

A.15 start root 3 end root
B.Start Fraction 15 over 2 End Fraction
C.5 start root 3 end root
D.Start Fraction 15 Start Root 2 End Root over 2 End Fraction

Answer 1

5 sqrt(3) =x

Explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp / adj

tan 30 = x/15

15 tan 30 = x

15 ( sqrt(3)/3) = x

5 sqrt(3) =x
