Answer:
42.6 degrees
Step-by-step explanation:
A supplementary angle is one that adds to the other one so the sum is 180 degrees. So 180-137.4=42.6
The triangle to the top right is missing one angle. We know the sum of all angles in a triangle add up to 180 degrees. We already have 35 + 90 = 125 degrees, so the last angle must be 55 degrees. That angle is verticle to another angle, which you should be able to notice (also 55 degrees because vertical angles are congruent). Now, we have 67 + 55 = 122 degrees in that triangle. It must add up to 180, so the unknown angle is 58 degrees.
Answer:
Step-by-step explanation:
We want to simplify:
We rewrite to get:
We now apply the laws of indices
We simplify to get
We leave our final answer is scientific form.
The final answer is therefore:
Answer:
A
Step-by-step explanation:
f(g(3)= f(g(x=3)) = f(
) = f(4/2) = f(2) = f(x=2) = 3*2-7 = 6-7 = -1
