1. Check picture 1. Let the one side of the triangle be a, drop one perpendicular, CD. Then triangle ADB is a right triangle, with hypothenuse a and one side equal to 1/2a. By the Pythegorean theorem, as shown in the picture, the height is

2. if a a=25 ft, then the height is

(ft)
3. consider picture 2. Let the length of the roof be l feet.
one side of the prism (the roof) is a rectangle with dimensions a and l, so the area of one side is a*l
the lateral Area of the roof is 3a*l
the area of the equilateral surfaces is

so the total area of the roof is

4. The total area was the 2 triangular surfaces + the 3 equal lateral rectangular surfaces. Now instead of 3 lateral triangular surfaces, we have 2.
So the total area found previously will be decreased by al
5. so the area now is

6. now a=25 and l=2a=50
Area=

=3041.3 (ft squared)
Answer:
Step-by-step explanation:
The square root of 8 to the nearest 100th is 2.83
The 3 is less than 5 so it does not alter the 8 at all.
The answer is 2.8
<span>The initial value is the value of the y-coordinate when the x-coordinate is equal to 0. That is the same to say the value at which the graph intercepts the y-axis. So, you justt have to pick the graph whose line intercepts the y-axis at 1/2. </span>
Answer:
C-D = <u>6</u>
A-B = <u>3.25</u>
D = <u>118</u>
Step-by-step explanation:
C-D = 6 because the line is the same as B-C
A-B = 3.25 because the line is the same as A-D
D = 118 because the angle of B is vertically opposite to D
Answer:-1
Step-by-step explanation:You do reverse operation so negative 2Y means multiplication so you divide two -2 sides so positive two divided by -2 is -1
