a truss For the roof of the house is constructed from two identical right angles each has a base of 12 ft and height of 4 ft Find the length of the third side of each truss. round your answer the th nearest 10th

Each truss has a third side length of 12.6 ft

Step-by-step explanation:

We'll use the Pythagorean Theorem, relating the three sides of a triangle with

a^2 + b^2 = c^2

The base and height are a and b respectively.

The third side (the hypotenuse) is c

So

(12)^2 + (4)^2 = c^2

144 + 16 = c^2

160 = c^2

c =

12.6 ft

the answer is a

step-by-step explanation:

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
