Answer:
6045000000000000000000000 kg.
Step-by-step explanation:
We have been given that the mass of Earth is kg. The mass of the Moon is
kg.
To find the total mass we will add mass of Earth and Moon.
First of all let us convert the given masses in standard form.
Therefore, the mass of Earth and Moon is 6045000000000000000000000 kg.

Step-by-step explanation:
(a)
Sum the parts of the ratio , 1 + 2 + 3 = 6 parts
Divide sum of angles in a triangle by 6 to find the value of one part of the ratio.
180° ÷ 6 = 30° ← value of 1 part of the ratio
2 parts = 2 × 30° = 60°
3 parts = 3 × 30° = 90°
Since there is an angle of 90° then the triangle is right.
(b)
The shortest side is the side opposite the smallest angle of 30°
Using the sine ratio and the exact value
sin30° = , then
sin30° = =
=
( cross- multiply )
2 opp = 19 ( divide both sides by 2 )
opp = 9,5
Shortest side in the triangle is 9.5 cm
