Question

The length of the missing side is: ?m

Answer 1

Answer:

85 ft

Step-by-step explanation:

for all right triangles, triangles with a 90 degree angle, the sides are equal to $a^{2} + b^{2} = c^{2}$ where c is the hypotenuse, or the longest side.

so... $40^{2} + 75^{2} = c^{2}$

$7225 = c^{2}$

c= 85
