Find length of each side

Option b: 10 in, 18.5 in, 31.5 in.

Explanation:

The three sides of a triangle are and

The perimeter of the triangle is .

Since, Perimeter = all sides of the triangle

Let us add all the three sides to determine the length of each side.

Substituting the value of Perimeter and simplifying, we get,

Substituting in the three sides of the triangle and , we get,

Thus, the lengths of each side are 10 in, 18.5 in, 31.5 in.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
