Anyways hope I helped
Answer:
x = 12
y = 12
z = 12
Step-by-step explanation:
The triangle with z as one of it's sides is a 30, 60, 90 triangle where the longest side of the triangle is 2x, the shortest side as x, and the middle side as x*sqrt of 3.
The shared line between the two triangle is 12 and z is 12*sqrt of 3
The left triangle is a 45, 45, 90 triangle where the 2 sides that look the same are the same and the hypotenuse is x sqrt of 2 so y is 12 and x is 12 sqrt of 2
3m+21=6m
=>21=6m-3m
=>21=3m
=>7=m
Therefore option A is the answer
It is equal. .21 ia the same as 21%
I think the alternative b is
