Answer:
5
Step-by-step explanation:
This is a right triangle, but note that you only know the measurement of one angle, which is 90 degrees.
Use the following formula to solve:
a² + b² = c²
In which:
a & b = shorter sides
c = hypotenuse
Plug in the corresponding numbers to the corresponding variables:
(3)² + (4)² = ?²
Solve. Remember to follow PEMDAS. First, solve the exponents, then add:
(3)² = (3 * 3) = (9)
(4)² = (4 * 4) = (16)
9 + 16 = ?²
25 = ?²
Isolate "?". Root both sides:
√(25) = √(?²)
? = √25 = √(5 * 5) = 5
Your missing side's measurement is 5.

Answer: 66s + 180
How:
17 s ^ { 1 } 2 + 32 s + 180
Calculate s to the power of 1 and get s.
17s\times 2+32s+180
Multiply 17 and 2 to get 34.
34s+32s+180
Combine 34s and 32s to get 66s.
Final answer should be 66s + 180
