Answer:
The length of YZ is 22.30mm.
Step-by-step explanation:
Basically we need to find the hypotenuse of the triangle, or the longest side.
The formula for finding the hypotenuse of a triangle is: c = √(a² + b²)
First we need to multiply 14.3 and 17.1 to the second power.
14.30 × 14.30 = 204.49
17.10 × 17.10 = 292.41
Now we add our two sums.
204.49 + 292.41 = 496.90
Now we need to find the square root of 496.90, which is 22.2912539.
Rounded to the nearest DP(Decimal point), it's 22.30
