Answer:

Step-by-step explanation:
90 + 40 = 130
180 - 130 = 50
When a triangle is rotated, it must be rotated through a center of rotation.
Assume the coordinate of LMN is



The rule of 180-degree rotation is:

So, we have:



See attachment for the graphs of LMN and L'M'N
<u>(a) Describe the transformation</u>
When triangle LMN is rotated 180 degrees across the origin, the x and y coordinates of LMN are negated to form triangle L'M'N'
<u>(b) Lines LL' and MM'</u>
The distance between point L and the center of origin is the same as the distance between point M' and the center of origin
Similarly, the distance between point L and the center of origin is the same as the distance between point M' and the center of origin
<u>(c) Line NN'</u>
Line NN' will assume the same characteristics as lines LL' and MM'

P(heads or tails) = 1 This is because when flipping a coin, there are only two possible answers, either heads ir tails so the probability of getting either one is 100%. However, if you're asking for P(heads) = 1/2, and P(tails)= 1/2.
Domain: f (x) is the set of all values for which the function is defined
range: the set of all values that f takes
