Answer:
2.6 feet
Step-by-step explanation:
The length of the base can be found using Pythagoras theorem.
Let the let of the base be represented as y
Given
The left side = 3 feet
Right side = 4 feet
Therefore 4^2 = 3^2 + y^2
4 x 4 = 3 x3 + y^2
16 = 9 + y^2
Subtract 9 from both sides
16 - 9 = 9 - 9 + y^2
7 = y^2
Or
y^2 = 7
y = squared root of 7
y = 2.6 feet
The length of the base is 2.6 feet
