Answer:
67°
Step-by-step explanation:
Corresponding angles are equal in parallel lines.
Here, ∠acb and ∠aed are corresponding angles for lines bc and de
hence ∠aed = ∠acb = 39
in triangle ade,
x + 74 + 39 = 180 (angle sum property of a triangle)
x = 67°
ANSWER
EXPLANATION
The given function is:
and
To find g(f(-1)), we substitute x=-1, to obtain;
We simplify the square in the denominator to get,
We now add the denominator to obtain;
