Answer:
Hypotenuse = 5.7 cm
Explanation:
Since the base is a right triangle, we would apply pythagorean theorem to find the length of the hypotenuse of the triangular base.
Pythagorean theorem is given as: c² = a² + b²,
Where,
c = hypotenuse
a = 4 cm
b = 4 cm
Substitute
(Hypotenuse)² = 4² + 4²
Hypotenuse = √32
Hypotenuse = 5.65685425
Hypotenuse = 5.7 cm (nearest tenth)
