Show all your work! the perimeter of an isosceles triangle is 7.5m, and the length of a leg is 2m. find the length of the base.

3.5 m

Step-by-step explanation:

The perimeter is the sum of the lengths of the three sides of the triangle, so is the sum of two legs and the base.

... 7.5 m = (2 m) + (2 m) + base

... 3.5 m = base . . . . . . subtract 4 m

base = 3.5m

Since the triangle is isosceles both legs are equal to 2m

base = 7.5 - 2 - 2 = 3.5m

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35
