Answer:

Option a. 30 units

Step-by-step explanation:

we know that

An equilateral triangle has three equal sides

so

XY=YZ=XZ

The perimeter of triangle XYZ is equal to

P=XY+YZ+XZ

P=3XZ

<u><em>Find the distance XZ</em></u>

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

we have

X is located at (-5, -9) and Z is located at (1, -17)

substitute the values in the formula

XZ=\sqrt{(-17+9)^{2}+(1+5)^{2}}

XZ=\sqrt{(-8)^{2}+(6)^{2}}

XZ=\sqrt{100}

XZ=10\ units

Find the perimeter

P=3(10)=30\ units

The probability is 2/25 or an 8% chance. By taking the probability of the fishers from Clearwater (56/70) and multiplying that by the probability of the non fishers from Mountain view (8/80) we can find the total probability of the situation.
