Answer:

Step-by-step explanation:
By definition, supplementary angles add up to 180 degrees. Therefore, we can set up the follow equation to solve for
:

Answer:
1.
T mBAC = mB'A'C'
F 2mABC = mA'B'C'
F BC = 2B'C'
T 2XA = XA'
2
D'(-2/3; -1)
E'(-1;1)
F'(1;1)
G'(1;-1)
3
the centre is L(0;-2)
the scale factor is 4
length J'K' = 4JK
the measure of L is equal the measure of L'

K(4;2) 4 4 16 16 0+16 -2+16 K'(16;14)
Answer:

Step-by-step explanation:
see the attached figure to better understand the problem
step 1
In the right triangle ADE
Find the value of h1
See the attached figure
h1=AD

Solve for h1

step 2
In the right triangle ABC
Find the value of h2
See the attached figure
h2=BC

Solve for h2

step 3
Find the height of the neighboring building
we know that
The height of the neighboring building is equal to

substitute the values

Round to the nearest tenth of a foot

"<" means the number on the left is smaller than the number on the right;
10am < b < 12pm
In this case that means "b" would be in between these times
let x be the number
2(x+5)= ±3(x-3)
2x+10= 3x-9 or 2x+10= -3x+9
x=19 or x=0.2
