10x - 18y = 84 6=x substitute 6 for x so its 6 * 10
60 - 18y = 84 subtract 60 from both sides
-18y = 24 divide by -18
y = -1 1/3
check!
60 + 24 = 84
84 = 84
Answer:
1/5
Step-by-step explanation:
In triangle b. we know that tan(x) = Opposite side to x angle / Adjacent side to angle x.
By substituting in above formula,
tan(x) = 12/5 = 2.4
x = tan^-1(2.4) = 68 degrees.
And in triangle a. i am not clear with the angle. Is it 51 or any other?
X=33
