I need help i dont understand how to do this!!​
Schach [20]

Answer:

16, see below :)

Step-by-step explanation:

Hello!

We can use the pythagorean theorem because one of the angles is 90 degrees. According to the theorem, a^2 + b^2 = c^2

a is 12, b is unknown, and c is 20

Now we use the theorem

12^2 + b^2 = 20^2

144 + b^2 = 400

b^2 = 256

b = sqrt(256)

b = 16

The length of the missing side is: ?m
victus00 [196]

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
