Answer:
24+4x
Step-by-step explanation:
4(6)= 24
4(x)= 4x
Answer:
Step-by-step explanation:
<u>Coordinates of the points C and D:</u>
The point E has coordinates of (x, y).
The point E is at 3/4 of CD from C and 1/4 of CD from the point D.
<u>Find coordinates of E:</u>
- x = -3 + 1/4(1 + 3) = -3 + 1 = -2
- y = -4 + 1/4(6 + 4) = -4 + 2.5 = -1.5
Let distance form the pole = x and height of the hill = y ft
now we can set up 2 equayions
tan 18 = (40-y)/x
tan 14 = y/x
from second equation y = sxtan14 so we have:-
tan 18 = ( 40 - x tan 14) / x
x tan 18 = 40 - x tan 14
x(tan 18 + tan 14) = 40
x = 40 / (tan18 + tan 14) = 69.66 feet Answer
Since AB is a straight line, and straight lines are 180 degrees, you can add the two 62 degree angles.
62+62=124
180-124=56
angle x is 56 degrees
I think the third (and last) answer is correct, because it would successfully eliminate the x variable when adding downwards. If you want me to explain in more detail feel free to ask :)
