Five fourths of a right angle

Five fourths of a right angle

A right angle is 90 degrees.

Five fourths is 

Five fourths OF A right triangle

OF 90 degrees

Of means multiplication so:



And that equals to 112.5

So your final answer is

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

That’d be 9 years or something
