For this case what we must do is use the law of cosines.
 We then have the following equation:
 c ^ 2 = a ^ 2 + b ^ 2 - 2 * a * b * cos (x)

 Where,
 a, b: sides of the triangle
 x: angle between sides a and b.
 Substituting values we have:
 c^2 = 90^2 + 75^2 - 2*90*75*cos(85)

 Clearing the value of c we have:
 c =  \sqrt{ 90^2 + 75^2 - 2*90*75*cos(85)}
 Answer:
 
An expression that is equivalent to how many feet the oak trees are from each other is:
 
c = \sqrt{ 90^2 + 75^2 - 2*90*75*cos(85)}

Question 2<br> Answer<br><br> Solve
Lelu [443]

<u>Answer:</u>

  • Option B is correct.

<u>Step-by-step explanation:</u>

<u>To subtract fractions, we must check if the denominators of both fractions are the same.</u>

  • 2/5 - 1/7
  • => 2 x 7/5 x 7 - 1 x 5/7 x 5
  • => 14/35 - 5/35

<u>Now, let's subtract for the result.</u>

  • => 9/35

Hence, <u>Option B is correct.</u>

Hoped this helped.

Hello!

Answer:

\large\boxed{C = 12\pi ft\text{ or } C = 37.68ft}

\text{Formula for the circumference of a circle:}

C = d\pi

\text{In this instance, d = 12 ft. Plug this value into the equation:}

C = 12\pi ft \text{ or } C = 37.68 ft (\pi = 3.14)

djverab [1.8K]

Answer:

The rectangular prism with these dimensions w = 3 cm, l = 5 cm, h = 5 cm has the largest volume.

Step-by-step explanation:

The formula for the Volume of a V = 3 * 5 * 5

V = l * w * h

V = 3 * 5 * 5

V = 75 cm³

The rectangular prism with these dimensions w = 3 cm, l = 5 cm, h = 5 cm has the largest volume.
