Hey there!
To solve this problem, you first would need to solve for how much of the cake is left after Jasmine, her friend, and Jasmine's brother got their slices. Then, you would need to split the remaining amount in half to get the answer of what each parent ate. We would need to make all of the denominators the same, so let's make all of the fractions out of 12, a common denominator of 3 and 4.



It can then be concluded that each parent ate

of the cake, since there was

remaining.
You can check this answer by adding up all of the parts we used in this problem:

Hope this helped you out! :-)
Answer:
The trigonometric ratios are presented below:





Step-by-step explanation:
From Trigonometry we know the following definitions for each trigonometric ratio:
Sine
(1)
Cosine
(2)
Tangent
(3)
Cotangent
(4)
Secant
(5)
Cosecant
(6)
Where:
- Adjacent leg.
- Opposite leg.
- Hypotenuse.
The length of the hypotenuse is determined by the Pythagorean Theorem:

If
and
, then the trigonometric ratios are presented below:





The error interval of the perimeter is 6.1 cm ≤ p < 6.15 cm
<h3>How to determine the error of interval?</h3>
The perimeter is given as:
P = 6.1 cm to 1 decimal place
The smallest number that can be approximated to 6.1 is 6.05, while the largest number is less than 6.15
This means that the interval is:
6.1 cm ≤ p < 6.15
