X, Y and Z are three points on a map. Y is 43km and on a bearing of 039° from X.
Z is 67km and on a bearing of 117° from X.
Calculate the distance between Y and Z rounded to 1 DP.

x = 16

Step-by-step explanation:

I could be wrong so sorry in advance lol but this is what I did:

I made the equation 3x + 3 = ((7x-10)/2)

I divided the 2nd equation by 2 so that it would be the same length as RZ.

after that, I got: 3x + 3 = 3.5x - 5

from there, i did basic algebra to get the answer 16

hope this helps!
