From my website, I have an online Kepler's Third Law calculator.
The formula is G · m · t² = 4 · π² · r³
I had to solve I have the formula solved for 'r', 't' and 'm' and I made a graphic of all three formulas. (see attached).
Anyway, since the formula is <span>G · m · t² = 4 · π² · r³ then we can solve for 'r'
</span>
<span>r³ = (G · m · t²) / (4 · π²) and therefore
r = </span><span>cube root [(G · m · t²) / (4 · π²)]

Answer:
Let angel C be a
now,
a+68°+37° = 180° ( sum of triangles)
or, a+ 105°=180°
or, a= 180°-105°
so, a= 75°
again,
a = x = 75° ( being alternate angle )
so, the required value of x is 75°
Because the student scored 73/100 on the first test, their current average is 73%.
To calculate the avergae with the next test score, you add both percentages the student gets together and then divide by 2.
79 = (73 + x) / 2
Multiply by 2 on both sides
158 = 73 + x
Subtract 73 on both sides
x = 85
So the student needs to get at least an 85/100 on the next test to maintain a 79 average.
