Answer:
Step-by-step explanation:
Divide the numerator and denominator by 4
What exactly are partial quotients? Normal divisions says the answer is twenty three
Answer: 212 feet
Have a look at the image shown below. On that image, I've marked key details to focus on. Namely, the bottom right triangle has the angle CAB equal to 27 degrees because of the congruent alternate interior angles. This is the reference angle we'll base everything off of.
Opposite this angle is the side BC = 108 which is the lighthouse height. Adjacent to this angle is AB = x which is unknown. The goal is to solve for x
Use the tangent rule
tan(angle) = opposite/adjacent
tan(angle CAB) = CB/AB
tan(27) = 108/x <--- substitution
x*tan(27) = 108 <--- multiply both sides by x
x = 108/tan(27) <--- divide both sides by tan(27)
x = 211.96 <-- see note below
x = 212
note: use a calculator that has the trig functions sine, cosine, etc. You'll use the tan function for tangent. Make sure your calculator is in degree mode. the result you get is approximate as shown above, which will round to 212 when rounding to the nearest whole number.
So first let’s multiply both sides by 10
Now we are left with this:
-4x-90<9
Now you want to move the -90 to the other side and when you do this you have to change the sign as well so now you have this:
-4x<9+90
Now add 9 and 90 together and you’ll get this:
-4x<99
Then divide both sides by -4 and flip the inequality sign
x>- 99/4
Your answer would be:
x>- 99/4
Hope this helps! :3
