Answer:
50
Step-by-step explanation:
Equilateral triangles have angles that all measure the same
180/3 = 60
so all angles measure 60
<c = 60
60 = x+10
Subtract 10 from each side
60-10 = x+10-10
x=50
If the decimal can't be written into a ratio, then it is not rational.
This is a basic subtraction problem :-).
You will subtract how much money the mechanic gives to the supplier; which in this case will be $20, by the total amount of the parts which is $14.56.
20-14.56 = 5.44
Therefore, he will receive $5.44 in change for the transaction.
By this equation: d = 4(32), we know what d equals, which means we have the value of d.
d= 4*32
d = 128
