Answer:
7.351
I don't know how they have rounded; the closest answer is A
Step-by-step explanation:
The only way I know to do this is with the cos law
y^2 = x^2 + z^2 - 2*x*z cos(Y)
x = 22
z = 16
y = ?
I have serious doubts that this will make a triangle. I ran it though a calculator and it does work -- surprise for me. Substitute the givens.
y^2 = 256 + 484 - 2*10*22*cos(13)
y^2 = 740 - 704*cos(13)
y^2 = 740 - 704*0.9744
y^2 = 740 - 685.95
y^2 = 54.05 Take the square root of both sides
y = √54.05
y = 7.351
Answer:
7.4
Step-by-step explanation:
The information given is in from SAS.
This is a job for law of cosines.
This is the law of cosines
The angle A is opposite side a and b,c are the other sides.
So 13 degrees is opposite the y there.
Now I'm going to put 16^2+22^2-2*16*22*cos(13) in my calculator:
Now one more step. To get rid of the square, you need to square root both sides:
Sp the answer is approximately 7.4
