The perimeter of a triangle is 65 meters. The second side is 5 meters less than the first side.The third side is 7 meters more than the first side. What is the length of each side?

Answers

Answer 1

Answer:

The length of each side of triangle is:

First side of triangle = 21 inches

Second side of triangle = 16 inches

Third side of triangle = 28 inches

Step-by-step explanation:

Perimeter of triangle = 65 meters

Let

First side of triangle = x

Second side of triangle = x-5 (The second side is 5 meters less than the first side.)

Third side of triangle = x+7  (The third side is 7 meters more than the first side.)

We need to find length of each side.

The formula used is:

[tex]\mathbf{Perimeter\:of\:triangle=Sum\:of\:all\:sides\:of\:triangle}[/tex]

Putting values and finding value of x

[tex]Perimeter\:of\:triangle=Sum\:of\:all\:sides\:of\:triangle\\65=x+x-5+x+7\\65=3x+2\\Switching\:sides\\3x+2=65\\Subtracting\:2\:from\:both\:sides\\3x+2-2=65-2\\3x=65-2\\3x=63\\Divide\:both\:sides\:by\:x\\\frac{3x}{3}=\frac{63}{3}\\x=21[/tex]

So, We get value of x = 21

Now, finding the length of each side of triangle:

First side of triangle = x = 21

Second side of triangle = x-5 =21-5 =16

Third side of triangle = x+7 = 21+ 7 = 28

The length of each side of triangle is:

First side of triangle = 21 inches

Second side of triangle = 16 inches

Third side of triangle = 28 inches

Answers

Answer:

39.6 ft.

Step-by-step explanation:

Height of the top of the goal post would be x + 5.5

So for we need to calculate x first,

For x:

[tex]tan\ \theta = \frac{perpendicular}{base}\\\\tan\ 61=\frac{x}{20}\\\\20*tan61=x\\\\x=20*1.732\\\\x=34.64\ ft[/tex]

So height of the top of the goal post would be 34.64 + 5.5 which is

39.64 ft. rounding it to nearest tenth would be 39.6ft.

y = -2x - 9 and 6x - 5y = - 19

Answers

Answer:

x = -4

Step-by-step explanation:

The first equation tells us what y is equal to. We then substitute wherever there is a y with what y equals.

y = -2x - 9

6x - 5y = -19

6x - 5(-2x-9) = -19

6x + 10x + 45 = -19

16x + 45 = -19

16x = -64

x = -4
