If they are congruent then angle C corresponds to angle T
tan(theta) = opposite side/adjacent side
So tan (theta) = 1000/4000= 1/4
so theta= arc tan(1/4)= 0.245 radians= 0.245*180/pi = 14degree
So option a is correct.
The number of kilometres travelled by the satellite in discuss in which case, the satellite makes 8 revolutions around the earth is; C = 177,271.8 km.
<h3>What is the distance in kilometres covered by the satellite after 8 revolutions?</h3>
Given from the task content, the earth's diameter is; 6371 km and since, the height at which the satellite orbits the earth is; 343km, it follows that the diameter of orbit if the satellite in discuss is;
D = 6371 + (343)×2
Hence, we have; diameter, D = 7057 km.
Hence, the distance travelled after 8 revolutions is;
C = 8 × πd
C = 8 × 3.14 × 7057
C = 177,271.8 km.

Answer:
22
Step-by-step explanation:
2x5 =10 4x3 = 12 12=10 =22
Answer:
D. None of these
Step-by-step explanation:
(5×10^8)(4×10^3)
=20 × 10^11
All the terms are being multiplied. There is no distributive property (FOIL) here. Rearrange the numbers in any order that helps you.
5 × 4 × 10^8 × 10^3
Add exponents to multiply the 10's.
and in proper scientific notation, one last change would give you
2.0 × 10^12
