Question

Please help. I need this one and my last question and im done​

Answer 1

The value of X is 4, and the area of the triangle is
`60^2 units`.

Explanation:

First we need to add up all the sides. Doing so will give us the equation
`8x+8=40`. Subtracting 8 from both sides will give us
`8x=32`. Next we divide both sides by 8 in order to isolate the variable, which gives us
`x=4.`

This gives us 4 as our value of x.

Now we need to find the area. Substituting x into the values for base and height will give us 8+7 = 15 for our height, and 4+4=8 for our base. 15*8 is 120, and divided by two gives us 60 as out area.

Thus, x=4 and area=60.
