Find the missing variable for a triangle: a=48in2

1 answer:

3 0

Assuming that the given triangle is a right triangle where height and base are equal, we can solve for the missing variables. Let us review the given problem, the given is the total area since unit of "a" is inch squared.

The formula for an area of a triangle is At = 1/2(bxh). We substitute the given value and assume that h=b.

Therefore, 48=1/2bh. To eliminate 1/2, we multiply both sides by 2. Then we have 96=bh. When b=h, we have b^2=96.

The missing variables are b=h=9.8.

charle [14.2K]

Answer:

the length of the ladder is 8.827ft

Step-by-step explanation:

We know that the angle formed between the floor and the stairs is 65 °

the height at which the ladder reaches is 8 feet

between the floor and the house we know that we have a 90 degree angle

so we have a right triangle with its 8 foot wall leg

and an angle of 65 degrees on the floor and the stairs

the length of the stairs in this triangle would represent the hypotenuse

we have the angle and measure of the opposite leg, we want to know the hypotenuse

it is known that the sine of an angle in a rectangular triangle is equal to the opposite leg on the hypotenuse

sin 65° = op / hyp

sin 65° = 8 / hyp

0.9063 = 8 / hyp

hyp = 8 / 0.9063

hyp = 8.827

The volume of a right cylinder is 7,448π cubic centimeters the diameter of the base of the cylinder is 28 centimeters what is th

Anarel [89]

By definition, the volume of a cylinder is given by:
V = π * r ^ 2 * h
Where,
r: radio
h: height
Clearing the height we have:
h = (V) / (π * r ^ 2)
Substituting values:
h = (7448π) / (π * (28/2) ^ 2)
Rewriting:
h = (7448) / ((14) ^ 2)
h = 38 cm
Answer:
The height in centimeters of the cylinder is:
h = 38 cm
