Answer:
415/619
Step-by-step explanation:
619 is a prime number, so the fraction is in simplest form already.
Z = 140
X = 40
Y = 40
Explanation:
Z and the angle given (140 degrees) are vertical angles, and are therefore congruent
We know that x and y are vertical angles, so they are also congruent to each other
You know that together, the angles have to add up to 360
140 + 140 + x + y = 360
Another way of putting it:
360-280 = 80
Now, we have to divide by two since we need to find x AND y
80/2 = 40
Therefore, your answers for x and y are 40
To double check, you can add up the angles and see if they equal 360
140 + 140 + 40 + 40
280 + 80 = 360
<em><u>Answer:</u></em>
(7, -5)
<em><u>Step-by-step explanation:</u></em>
We can see the dot, is 7 units to the right of the y axis, and 5 down from the x-axis. We then can create the coordinates because we know where it is:
If it is on the right side of the y-axis, it is positive. If it is below the x-axis, it is negative so:
(7, -5) would be the coordinate point

<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
The surface area of pyramid = sum of individual area of the surface
Surface area = (2 * 2) + 4(0.5 * 2 * 3)
The expression that shows the surface area of the pyramid is (2 * 2) + 4(0.5 * 2 * 3)
