To find x we are gonna use the cosine formula.
Cos 0 = adj/hyp
0 represents theta
Cos 0 = adj/hyp
Cos 0 = 25/40
Convert 25/40 to decimal from
25/40 = 0.625
On a scientific calculator press the key “2nd F” or “Shift” then “cos”(which would give cos inverse) then type 0.625 equal.
Cos-1 0 0.625
= 51.31 degrees
x is therefore 51.3 degrees to the nearest tenth

Answer:
D. X=7
Step-by-step explanation:
Use the order of operations to solve this problem.
First, combine like terms.
7x-5x=2x
Our equation is now 2x-3=x+4
Now, add 3 to both sides.
Our equation is now 2x=x+7
Subtract x from both sides.
x=7
The answer is D. X=7
