An isosceles triangle has two sides of equal length, a, and a base, b. the perimeter of the triangle is 15.7 inches, so the equation to solve is 2a + b = 15.7. if we recall that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side, which lengths make sense for possible values of b? select two options. –2 in. 0 in. 0.5 in. 2 in. 7.9 in.

Step-by-step explanation:

we have

Verify each case

case A)

this length does not make sense for a possible value of b

case B)

this length does not make sense for a possible value of b

case C)

Find the value of a

Verify the triangle inequality theorem

-----> is true

-----> is true

therefore

this length does make sense for a possible value of b

case D)

Find the value of a

Verify the triangle inequality theorem

-----> is true

-----> is true

therefore

this length does make sense for a possible value of b

case E)

Find the value of a

Verify the triangle inequality theorem

-----> is true

-----> is not true

therefore

this length does not make sense for a possible value of b

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
