Answer:
x = 15°
Step-by-step explanation:
These angles form a linear
4x - 17 + 137° = 180°
4x - 17 = 43°
4x = 60°
x = 15°
Answer: That seems right. Maybe you didn't simplify. Then, it would be 8/11.

1. Minimum = 4
2. First quartile = 6.5
3. Median = 13.5
4. Third quartile = 19
5. Maximum = 20
<u>Explanation</u>
To calculate the measure of central tendency, you first arrange the set of the data in ascending order.
The set of data given will be;
4, 4, 9, 9, 18, 18, 20, 20.
Part 1:
The minimum value of the data is 4.
Part 2:
The first quatile is the median of the lower half which is comprised by:
4, 4, 9, 9
1st quartile = (4+9)÷2
= 13÷2
= 6.5
Part 3:
Median of the data is;
Median = (9+18)÷2
=27÷2
= 13.5
Part 4:
3rd quartile is the median of the upper half which comprises of;
18, 18, 20, 20.
3rd quartile = (18+20)÷2
= 48÷2
= 19
Part 5
The maximum of the set of data is 20.
The value of tangent theta is equal to the negative 1. At this value the value of secant theta is
.
<h3>What is tangent theta?</h3>
The tangent theta in a triangle is the ratio of sine theta and cos theta. It can be written as,

Given information-
The value of tangent theta is equal to the negative 1.

The tangent theta in a triangle is the ratio of sine theta and cos theta. It can be written as,

The value of tangent theta is equal to the negative 1. Thus put the value in above expression as,

Simplify it further as,

When the value of cosine and sine theta is equal, then the angle exist in 4th quadrant with the value of
. Which extent to the
for the cosine function.
In the trigonometry cosine theta is the reciprocal of the secant theta. Thus,

Thus the value of secant theta is

So, if the first person takes half of the pizza, half of the pizza is left.
If the second person takes half of the amount the first person took, that would be a quarter of the pizza left.
TL;DR - There is 1/4 of the pizza left
