Answer:
180
Step-by-step explanation:
to find the side of the smaller triangle you do x
and get 3600. Then do
and get 60. Since the larger triangle is 3 times that size you do 3 x 60 and get 180.
How to solve -10|-5x-4|-10=-20
2 answers:
Answer:
x = 1 or x =
Step-by-step explanation:
given
- 10 | 5x - 4 | - 10 = - 20 ( add 10 to both sides )
- 10 | 5x - 4 | = - 10 ( divide both sides by - 10 )
| 5x - 4 | = 1
The absolute value always returns a positive value, however, the expression inside can be positive or negative, hence
5x - 4 = 1 ( add 4 to both sides )
5x = 5 ( divide both sides by 5 )
x = 1
OR
5x - 4 = - 1 ( add 4 to both sides )
5x = 3 ( divide both sides by 5 )
x =
Solutions are x = 1, x =

Answer:
The scientist can calculate the distance between the moon and the sun using trigonometric ratio of Cosine.
Step-by-step explanation:
We have been given that the moon forms a right triangle with the Earth and the Sun during one of its phases.
We can see from our graph that the distance between Sun and Moon is the hypotenuse of the right triangle as it is the opposite side of right angle formed with the Earth.
The distance between Earth and Sun (y) is the adjacent side for our angle x degrees.
Since we know that the cosine of an angle is the trigonometric ratio of the adjacent side to the hypotenuse of a right triangle containing that angle.
Therefore, using trigonometric ratio Cosine, the scientist can calculate the distance between the Moon and the Sun.
