Answer:
The correct answer is 4 (0.72n)
Total notebook = 70
Total cost = 50.4
now
cost of one note book = total cost / total no notebook
= 50.4/70
= 0.72
Answer:
D. ⅘
Step-by-step explanation:
According to the acronym for trig ratio, SOHCAHTOA, we know that:

In the triangle given,
Opposite = √(20² - 12²) = √256 = 16
Hypotenuse = 20
Thus:

Simplify

Answer:
a = 60
Step-by-step explanation:
90 + 30 = 120
120 - 180 = 60
<u>Given</u>:
The measures of the alternate exterior angles are (180 - x)° and x°
We need to determine the value x that makes m ║ n
<u>Value of x:</u>
We know that the measures of alternate exterior angles are equal.
Thus, we have;

Adding both sides of the equation by x, we have;

Simplifying, we get;

Dividing both sides of the equation by 2, we have;

Thus, the value of x is 90.
Hence, the value x = 90 makes the alternate exterior angles congruent and hence the line m is parallel to n.
