The angles of elevation of an airplane between two observation points, A and B, are 30 ° and 45 ° respectively. If the vertical

Serjik [45]

Answer:

xA = 10 km

xB = 7.071km

Step-by-step explanation:

A/Q

p=5km

For point A

∅ = 30°

sin ∅ = p/h

sin 30° = 5/h

1/2 = 5/h

h = 5×2

h=10km

For point B

sin ∅ = p/h

sin 45° = 5/x

1/√2 = 5/x

x = 5 × √2

x = 7.071 km

.: Points A and B are 10 km and 7.071 km away from the airplane.

Find the slope of Line CD.<br> CD with C(-4, 4) and D(5, -8)<br> What is the slope of this?

ASHA 777 [7]

Answer:

-4/3

Step-by-step explanation:

Moving from C(-4, 4) and D(5, -8) we see that x (the 'run') increases by 9 and that y (the 'rise') decreases by 12. Thus, the slope m is rise/run, or

m = -12/9 = -4/3
