The length of the unknown sides of the triangles are as follows:
CD = 10√2
AC = 10√2
BC = 10
AB = 10
<h3>Triangle ACD</h3>
ΔACD is a right angle triangle. Therefore, Pythagoras theorem can be used to find the sides of the triangle.
where
c = hypotenuse side = AD = 20
a and b are the other 2 legs
lets use trigonometric ratio to find CD,
cos 45 = adjacent / hypotenuse
cos 45 = CD / 20
CD = 1 / √2 × 20
CD = 20 / √2 = 20√2 / 2 = 10√2
20² - (10√2)² = AC²
400 - 100(2) = AC²
AC² = 200
AC = √200 = 10√2
<h3>
Triangle ABC</h3>
ΔABC is a right angle triangle too. Therefore,
Using trigonometric ratio,
cos 45 = BC / 10√2
BC = 10√2 × cos 45
BC = 10√2 × 1 / √2
BC = 10√2 / √2 = 10
(10√2)² - 10² = AB²
200 - 100 = AB²
AB² = 100
AB = 10

Dear Noora7939, the pair of planets that exerts the strongest gravitational force is Saturn and Jupiter, since we know that both Jupiters are the same mass, we'll excuse that. Since the laws of gravity says that the bigger the mass the stronger the gravitational pull, Saturn has the stronger gravitational pull since Saturn is bigger than Mars.
Step-by-step explanation:
l dont understand your question
is it 3 and a fifth or 31/5
The correct answer is 2.5×10^2
Hope this helped :)
