Answer:
Step-by-step explanation:
To find measures of angles m and n
The triangle to the left has three sides of equal length.
This means that it will also have three angles of equal measure.
The internal angles of a triangle sum to 180°
So the internal angles of the left triangle are 180/3 = 60°
The top right angle is made up of one of the 60° angles and angle n
60 + n = 90
n = 30°
Again the internal angles of a triangle sum to 180°, so the right triangle
m + n + 90 = 180
m = 180 - 90 - 30
m = 60°
or we could realize that the top and bottom horizontal lines are parallel because the vertical line on the right makes right angles to both of them.
Knowing that they are parallel, we also know that angle m and the top right 60° angle of the left triangle are opposite internal angles of a line intersecting parallel lines and must be identical angles, therefore
m = 60°
Answer: To simplify an expression means to write an equivalent expression which contains no similar terms. This means that we will rewrite the expression with the fewest terms possible.

Answer:
80°
Step-by-step explanation:
The opposite angles of an inscribed quadrilateral add up to 180.
(2x + 13) + (3x + 37) = 180
(2x + 3y) + (5y) = 180
Solving the first equation:
5x + 50 = 180
5x = 130
x = 26
Solving the second equation:
2x + 8y = 180
2(26) + 8y = 180
52 + 8y = 180
8y = 128
y = 16
5y = 80. So ∠D = 80°.

Step-by-step explanation:
Transformations of Graphs (functions) is the process by which a function is moved or resized to produce a variation of the original (parent) function.
<u>Transformations</u>
For a > 0








Identify the transformations that take the parent function to the given function.
<u>Question 7</u>


Comparing the parent function with the given function, we can see that 5 has been <u>subtracted from the parent function</u>.
Therefore, the transformation is:

<u>Question 8</u>


Comparing the parent function with the given function, we can see that the <u>parent function has been multiplied by -1</u>.
Therefore, the transformation is:

<u>Question 9</u>


Comparing the parent function with the given function, we can see that the <u>parent function has been multiplied by 5.</u>
Therefore, the transformation is:
