Answer: Isolate the variable by dividing each side by factors that don't contain the variable. x=−4
Step
Answer: 130.8 degrees
Explanation:
The problem can be solved by using the cosine theorem:
(1)
where
a,b,c are the lengths of the three sides of the triangle
is the angle between b and c
In this problem, we can identify a,b,c, with:
a = XZ = 11.05
b = XY = 6.32
c = YZ = 5.83
So, the angle corresponds to the angle m∠Y. Re-arranging eq.(1), we find
So, the angle is
Answer:
16
Step-by-step explanation:
X-2/x-9=2
(X-2)=(x-9)2
X-2=2x-18
X-2X=-18+2
-X=-16
X=16
So value of X is 16.
