Solve for the missing side round to the nearest 10th (look at image)
SIZIF [17.4K]

Answer:

14.3

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2   where a and b are the legs and c is the hypotenuse

14^2 + 3^2 = c^2

196 + 9 = c^2

205 = c^2

Take the square root of each side

sqrt(205) = sqrt(c^2)

14.31782106 = c

Rounding to the nearest tenth

14.3 = c

What is the value of x?
Elanso [62]
Since all the angles are congruent, the sides must be congruent too.


So, just have one equation on one side equal to another.

5x= 3x+6

Subtract 3x from both sides.

2x=6

Divide 2 into both sides.

x=3.

We can check this by seeing if all the sides are the same.

5(3)= 15

6(3)-5= 15

3(3)+6= 15

At the beginning of the season, MacDonald had to remove 5 orange trees from his farm. Each of the remaining trees produced 210 o
Rainbow [258]

he initial number of trees was 204.

<h3>How to find the initial number of trees?</h3>

The first step to finding the initial number of trees is to write an equation that represents the situation.

  • T is equal to the initial number of trees.
  • 5 trees were removed = t - 5
  • Each tree produces 210 oranges = (t-5) (210)
  • The total of oranges is 41,780 = (t-5) (210)= 41,780

  • Solve the equation:

  • (t-5) (210)= 41,780
  • t-5= 41,780 / 210
  • t-5 = 198.95
  • t = 198.95 + 5
  • t = 203.9

This number can be rounded as 204.
