PQR is an isosceles triangle with PR = PQ.
(5x -4°
(x + 52)
Calculate the value of y.

Step-by-step explanation:

As two sides are equal so angles opposite to these are also equal, hence

5x-4=x+52

4x=56

X=14

Now,

R=5x-4

R=66

And,Q=x+52

Q=66(we already knew both angles are equal)

Now as sum of all angles of triangle equal 180 so,

66+66+P=180

P=48

its 50 miles away from the starting point

the answer is:

mean: 6

mad: 2.14
