1: the ladder
2: the walls
3: the ground from the wall to the ladder
Answer:
Step-by-step explanation:
<u>Use the formula:</u>
- A = 1/2Pa, where P- perimeter, a - apothem
<u>Find the area:</u>
- A = 1/2(5*17.6)*12.1 = 532.4 in²
Correct choice is d
Answer:
As this is triangular height and floor length we multiply and divide by 2 (representing halving the square)
= 3.5 x 6= 19 19/2 = 9.5ft
To thereafter measure the angle we can see 9.5/3.5 =2.711
so we have 90, 27 and 63 degree.
As this is decimal we round up to 30 degree. and round down to 60 degree.
Step-by-step explanation:
Answer:
Slope of line A is 1/3
Equation of Line B is y = 2x + 4
