Answer:
x = 144
Step-by-step explanation:
The sides and angles of a triangle can be determined using trigonometry ratios
The values of x, y and z are , and
<h3>How to determine the missing values of the triangle</h3>
The upper triangle is a right triangle with an angle measure of 45 degrees.
So, the value of x is:
Next, we calculate the hypotenuse (h) of the lower triangle using:
So, we have:
Take the square roots of both sides
The value of y is then calculated using the following sine ratio
Make y the subject
Evaluate
The value of z is then calculated using the following cosine ratio
Make z the subject
Evaluate
Hence, the values of x, y and z are , and

Answer:
1000
Step-by-step explanation:
if you were rounding it would be 1380, 1400, or 1000 because it isn't over 5
The table follows a linear pattern
The equation that represents the date on the table is C=0.25m + 8.95
<h3>What are linear patterns?</h3>
Linear patterns are equations that have constant rates or slopes
<h3>How to calculate the equation</h3>
From the table, we have the following ordered pair
(m,C) = (50,21.45) and (100, 33.95)
We start by calculating the slope using:
So, we have:
The equation is then calculated using:
So, we have:
Open the bracket
Hence, the equation of the total cost is C=0.25m + 8.95
