Answer:
The second leg of the right triangle is about 9.4.
I think it is 16 I am not sure because I did not do it I am just guessing
By the Law of Sine,

Solve for x and get x = 65.7.
It’s the first answer, both expressions equal 5 when substituting 2 for x because the expressions are equivalent.
1/2 of x +4
=1/2(2)=1.
1+4= 5
2+6=8
1/2(2)=1.
8-1=7
7-2=5
