Find the value of X for the triangle (Show all work, triangle and equations in picture)

Mathematics
1 answer:
kozerog [31]3 years ago

Answer:

x=5

Step-by-step explanation:

The perimeter of a figure is the sum of all its sides.

The sides are x, (x+3), and (2x). The perimeter is 23, so the sum of the expression equates to 23. Thus:

x+(x+3)+(2x)=23

Combine like terms:

4x+3=23

Subtract 3 from both sides:

4x=20

Divide both sides by 4:"

x=5

And we're done!

Find the value of x. If necessary, round to the nearest tenth.
Ghella [55]

Answer:

x = 10.3 in

Step-by-step explanation:

To find the value of a, use the area formula for a triangle. The formula is A = 1/2 *b*h. Here b = x and h= x. The formula becomes A = 1/2 *x². Substitute A = 53 and solve for x by using inverse operations.

A = 1/2x²

53 = 1/2x²

106 = x²

√106 = x

10.3 = x
