Answer:
(6,2)
Step-by-step explanation:
When solving a system of simultaneous equations, we want to see where the graphs intersect.
2x+5y =22 is the red line
x+y = 8 is the green line
They intersect at a point
The point is x=6 y=2
(6,2)
Answer:
70.3km
Step-by-step explanation:
When the bearings are visualized and the points connected as a triangle, The angle x would be the difference of the both bearings from x
i.e 117-41 = 76
Using cosine rule,
YZ²= 43² + 67² - 2 x 43 x 67
cos76
YZ= √4944
= 70.3
