Step-by-step explanation:
Hi there!
In this right triangle, we're given an angle and the opposing side, and we're trying to solve for the length of the hypotenuse.
In this situation, we can use the sine ratio:

Plug in the known information

Therefore, the length of the missing side is 49.0 units when rounded to the nearest tenth.
I hope this helps!
Answer:

Step-by-step explanation:
It is given that,
The average distance between the Earth and the Moon is 384 400 km.
We need to express in in standard form.
1 km = 1000 m
It means,
384400 km = 384400000 km
or
= 
Hence, the average distance between the Earth and the Moon is
.
Answer:
The standard form of a parabola is
y=ax2+ +bx+c, where a≠0.
To find the vertex, you need to find the x- and y-coordinates.
