Find . I think it has to do with the short side being 2/3 the long side but idk?

The value of x is 10.5

Solution:

Given RST is a triangle.

BC bisect the triangle RST.

SC = CR and SB = BT

This implies that BC is the mid-segment of ΔRST.

By mid-segment theorem:

Mid-segment = Half of the parallel side

Multiply by 2 on both sides.

Add 10 on both sides.

Subtract x from both sides.

Divide by 2 on both sides.

x = 10.5

The value of x is 10.5

easy math just plug in a and b

step-by-step explanation:

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
