5.08 cm to two decimal places

Step-by-step explanation:

The perimeter of the triangle is 10 3/4 cm

An isosceles triangle has two equal sides.

If one of these equal sides is 2 5/6 cm, we know that the other equal side is going to be the same length.

So far, 2 5/6 cm + 2 5/6 cm = 5.66666666667 cm.

10 3/4 cm is equal to 10.75 cm.

Since the perimeter is all the side lengths added together, we can subtract the sum of the two equal sides to find the third side.

10.75 cm - 5.66666666667 = 5.08333333333 cm

to two decimal places, this would be 5.08 cm.

it should be a.
