V=ca times height
1040=40 times h
H=1040 divide by 40
Height=26
A) 18x2 = 36
hope I helped
Best of luck :)
I believe this is pythag
15^2 x 11^2 = 27225
(square root) of 27225 = 165
165ft
It's a complementary angle, so just solve for x and subtract the CBD from 90,
First, we have to solve for x.
2x + 14 + x + 7 = 90
Combine like terms
3x + 21 = 90
Balance, subtract 21 from each side.
3x = 69
Divide 3 from each side
x = 23.
So know that we know x is 23, we can go about it 2 ways, subtracting the other angle with 90 or just substituting the variable, I'd just substitute the variable for it so just do 23 + 7. That equals 30, angle ABC = 30.
<u>Supplementary:</u> N and M & N and I
Supplementary angles: A pair of angles whose sum is equal to 180°.

<u>Vertical:</u> M and I
Vertical angles: A pair of opposite angles that are made by two intersecting lines.
<u>Complimentary:</u> None
Complimentary angles: A pair of angles whose sum is equal to 90°.
Hope this helps! :D
