3c^3. This is probably it. I'm pretty positive.
Answer:
x = 18 degrees
Step-by-step explanation:
We are given 72 degrees. The box on the bottom left of the ramp is at a 90 degree angle. Given that this triangle will add up to 180 degrees no matter what we add the two given degrees; 72 + 90 = 162. Now we subtract; 180 - 162 = 18 degrees.
X² + x + ...m
x² + x + 1/4
\/x² = x
\/(1/4) = 1/2
2*x*1/2 = 2x/2 = x
x² + x/2 + 1/4
Notice that
and given that 10 is closer to 9, it's clear that
is probably closer in value to 3 then to 4. (The actual value is indeed about 3.162.)
Is a supposed to be the answer? Is there any other options to choose from the no given list?
