Right triangle means:
sin, cos, and tangent
Here, we can see that:
sin 35° =

Simplify.
20sin 35° = x
Multiply 20 by sin of 35 degrees.
x = 11.47(ROUNDED)
Answer: Choice C
First you have to canceled out the fours from both side 4x/4-12/4 so x=3 then you do the same thing to the 7x-18
4x-12.
4x/4-12/4. So x=3
The fours cancelled out
7x-18
7x/7-18/7. So x= 2 4/7
The sevens cancelled out
