Answer:the area of triangle ABC is
346.4 feet^2
Step-by-step explanation:
The given triangle ABC is shown in the attached photo.
The formula for determining the area of a triangle is expressed as
Area = 1/2(abSinC) = 1/2(bcSinA)
A = 60 degrees
b = 40 feet
c = 20 feet
Therefore, area of the triangle is
1/2(bcSinA) = 1/2(40 × 20 × Sin60)
= 1/2 × 40 × 20 × 0.8660
= 346.4 feet^2
Alternatively, we can apply Heron's formula. We would determine the length of a by applying cosine rule,
a^2 = b^2 + c^2 -2bcCosA
Then, Heron's formula is expressed as
Area = √S(S - a)(S- b)(S - c)
Where S = (a + b + c)/2
Answer:
(-1,5)
Step-by-step explanation:
Take the Distance between B and M which is 2 up and 2 across. with that and following the information where M is a midpoint follow the patter of 2 up and 2 across to get A

Let the bushels of wheat is b and weight of the wheat is w.
We can say that more the bushels of wheat more will be the weight of the wheat.
Hence, the quantities vary directly.
Therefore, we have
, where k is the constant of variation.
Now, we have been given that 5 bushels of wheat weigh 136 kg. Thus, we have
Thus, the constant of variation is
Now, we have been given 3.5 bushels of wheat. Hence, we have
Therefore, 3.5 bushels of wheat weigh 95.2 kg
1. (16,25)-(24,5) the interval it falls from is 25 mph to 5 mph or it decreased by 20 mph.
2. From D (24,5) to E (28,45). The interval of time from point D to point E is 5 mph to 45 mph. or it increased by 40 mph.
3. From B (6,25) to C (16,25) and the constant rate is 25 MPH.
I'm not 100% sure about the everything.
