If you're using 7.6 percent, then you're not using 92.4 percent (100-7.6)
To find 92.4 percent of 67.8 billion do:
67,800,000,000*.924=<span>62,647,200,000 </span>
Number 3 is 7
Number 4 is 3
And number 6 is 9
Im sorry I dont know the rest.
I hope this helps.
There are three more angles with the same measure. A pair of corresponding angles and a pair of vertical angles.
The sum of the 3 inside angles of a triangle need to equal 180.
Y = 180 - 90 - 48 = 42 degrees.
