Answer:
Part A:
A pair of linear equations can only have one solution or infinitely many solutions. In this case, there would only be one solution as they intersection at only one point.
Part B:
The solution would be (3, 4) because it is the point of intersection between the two linear lines.
Answer:
20.1 feet
Step-by-step explanation:
sin = opp/hyp
sin85 = 20/x
xsin85 = 20
x = 20/sin85 ≈ 20.07
Answer:
height = h = 987.92
Step-by-step explanation: See Annex
The official Visual Flight Rules require more than 1000 ft , as a distance between the ground and bottom of clouds, for a plane to fly without instrumentation
We have to determine, with available data if we are in position of that distance
If we look at picture (in annex ) tangent of the elevation angle 51⁰ is
from tables tan 51⁰ = 1.2349 and we know tan ∠α = opposite leg/ adjacent leg
then
tan 51⁰ = 1.2349 = h/ 800
h = 987.92
So we don´t have enough height to let flying without instrumentation
Answer:
H
