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:
After 167 miles the Budget rental deal would be better than the U-haul deal
Step-by-step explanation:
Let <em>x</em> be the number of miles.
Considering the U-haul plan the cost can be expressed as:
![u=29.95+0.28x](https://tex.z-dn.net/?f=u%3D29.95%2B0.28x)
Consider the Budget rental plan the cost can be expressed as:
![b=34.95+0.25x](https://tex.z-dn.net/?f=b%3D34.95%2B0.25x)
For the Budget rental plan to be better than the U-haul plan the relation between the two cost equation will be:
![b](https://tex.z-dn.net/?f=b%3Cu)
Substitute the equations of <em>u</em> and <em>b</em> and solve for <em>x</em>:
![b](https://tex.z-dn.net/?f=b%3Cu%5C%5C34.95%2B0.25x%3C29.95%2B0.28x%5C%5C34.95-29.95%3C0.28x-0.25x%5C%5C5%3C0.03x%5C%5C0.03x%3E5%5C%5Cx%3E166.67%5Capprox167)
So after 167 miles the Budget rental deal would be better than the U-haul deal.
X meaning the letter X that’s how math works OR either X as for multiplication so it would be like -80x get it or no
