Answer:
Step-by-step explanation:
TQ = QR
Ray t bisects TR. TR is divided into two equal parts
5^2 + 12^2 = c^2
25 + 144 = c^2
169 = c^2
take the square root of both sides
+ - 13 = c
Step-by-step explanation:

is the required answer
The probability of finding one of the two defective fuses is:

The probability of finding 2 defective fuses is:

Therefore the probability of rejecting is 0.3117 + 0.026 = 0.3377.
The law of sines can be used to find the missing side lengths.
... RP = sin(60°)/sin(45°)·10 = 10√(3/2) ≈ 12.247
... PS = sin(75°)/sin(45°)·10 ≈ 13.660
Then the perimeter is
... perimeter = RS + RP + PS
... = 10 + 12.247 + 13.660 ≈ 35.91 . . . .units
