Hmm let's say
c = commercial launches
n = non-commercial launches
we know the total of launches were 53 for that year, so
c + n = 53
we also know that, whatever "c" is, "n" is "<span>was one more than three times" that
so... three times "c", 3 * c or 3c
one more than that?
3c + 1
so.. whatever "c" is, n = 3c + 1
</span>
<span>
solve for "c", to see how many commercial launches were there
what about "n"? well, n = 3c + 1</span>
Pythagorean theorem is applied to the right triangles.
Pythagorean theorem is a²+b²=c².
a is the length is the leg, b is also a leg and c is the hypotenuse
It is simplified. You can't simplify farther.
answer is equal to 82 coz x =9 and y=1
