42/6 but if you want to simplify, it's 7
Step-by-step explanation:
length of mall=84m
length of post office=38m
how much longer is the mall than the post office=84-38= 46m
275,000 km
The moons A, B, C form a right triangle with AC forming a hypotenuse with the diameter of the planet and the distance of both moons from the surface. So add A to the surface, plus the diameter of the planet, plus surface to c.
115000+45000+115000 = 275000
It’s 180-135 which equals 45 so it is 45 degrees for X
(7+x)+x=15
I did trial and error to get x=4.
