Answer:
h = 170 ft
Step-by-step explanation:
Let A represent the area, b the base and h the height of this triangle. The area formula is
A = (1/2)(b)(h).
Here A = 6000 ft^2 = (1/2)(80 ft)(h).
Solve this for the height, (h):
6000 ft^2 = (40 ft)(h), or
6000 ft^2
h = ---------------- = 150 ft
40 ft
Now we know the leg lengths: 150 ft and 80 ft.
Use the Pythagorean Theorem to find the length of the hypotenuse:
h^2 = 80^2 + 150^2, or
h^2 = 6400 +22500 = 28900
Taking the square root of this figure, we get the length of the hypotenuse:
h = 170 ft
Answer:
42.21 ft^2
Step-by-step explanation:
The formula: A=1
/2b √ c2﹣b2
c=hypotenuse
b=base
Answer:
EF>DF
Step-by-step explanation:
Big angles=big opposite sides
small angles=small opposite sides
angle d=big
angle e=small
EF>DF
The answer will be No, it is not a valid inference because his classmates do not make up a random sample of the students in the school. Hope it help!
Answer:
The slope of line AB is ( 3 - 5 ) / ( - 3 + 3 ) = ( - 2 ) / 0 = - ∞;
Therefore, Line AB has slope that is undefined.
