5/8 is the difference if u make common denominators
To ease your live re write each one by using sin, cos, tan, knowing well that:
cscx = 1/sin x ( sin of an angle = opposite side/hypotenuse(23)
secx = 1/cos x (cos of an angle = adjacent side/hypotenuse(23)
cotx = 1/tanx (tan of an angle = opposite side/adjacent side)
Work it out & if you have difficulties do let me know
Answer:
Step-by-step explanation:
S 50 m = 0.050 km
A ∵ 1 m = 100 cm
∴ 5 m = 500 cm
K ∵ 1000 dm = 0.1 km
∴ 1 dm = 
km
∴ 5246 dm = 
km
= 0.5246 km
P ∵ 1 m = 1000 mm
∴ 5.246 m = 5246 mm
P ∵ 1 hg = 1000 dg
∴ 3.7 hg = 3700 dg
U ∵ 1 g = 100 cg
∴ 0.37 g = 37 cg
E ∵ 1 kg = 1000 g
∴ 370 kg = 370,000 g
Because the time right at launch equals 0 (0 seconds have passed since the launch) solve the equation for 0.
-5(0 + 1)(0 - 9)
-5(1)(-9)
-5(-9)
45
The object was 45 metres above the ground at the time of the launch.
