Question

What is the value of x?

A. 6
B. 6 square root of 2
C. 12
D. 12 square root of 2

Answer 1

c because 6 times 2 equals 12

Answer 2

You would use the sine function
sin(x)=opposite/hypotenuse
sin(45)=6√2/x (cross multiply)
x*sin(45)=6√2
x*√2/2=6√2 (multiply both sides by 2)
x*√2=12√2 (divide both sides by √2)
x=12 so C

Hope this helps
