Answer: C. 17.5 feet
Step-by-step explanation:
The attached photo shows the triangle ABC formed by the ladder and the wall. It is a right angle triangle because one of its angles is 90 degrees. The ladder is the hypotenuse of the triangle. To determine the height of the wall, we would find BC by applying Pythagoras theorem
Hypotenuse^2 = opposite ^2 + adjacent^2
18^2 + 4.5^2 + BC^2
BC^2 = 324 - 20.25 = 303.75
BC = √303.75 = 17.5 feet.
Answer:
triangle ABC was translated up 4units and left 4 units
Step-by-step explanation:
1/2 dozen pencils in 1/3 box
what about 1 dozen
we cross miltiply this to get
1/3*2=2/3
doing the same for all the questions we get
1/4*5/4=5/20
3/4*5/3=15/12
3/10*12/7=18/35
Answer:

ANSWER
EXPLANATION
The given line passes through;
(-1,-1) and it is parallel to x + y = 3.
This line given to us can be rewritten as
y=-x+1
It has slope m=-1.
The line parallel to this line also has slope m=-1.
We obtain the equation of the line using the formula:
We substitute the slope and the point to obtain:
The equation of the line is
