Answer:
Step-by-step explanation:
Ratio of Cos C using the trigonometric ratios formula, would be:
Adjacent = BC = 40
Hypotenuse = AC = 41
Plug in the values
7 > 24/4 because 24/4=6 and 7 is > than 6
Look at the fractions!
9/10 is less than 1.
10/9 is more than 1. So it must be more than 9/10.
Answer:
The roots are rational
Step-by-step explanation:
Given
x² = 144 ( take the square root of both sides )
x = ± = ± 12 ← both rational
A rational number can be expressed in the form
where a and b are integers.
12 = ← thus rational
- 12 = ← thus rational
