2x+38=180
2x=142 (or x+x=142 from which 2x=142)
x=71
The unknown angles are each 71
You know this answer is logical as, since two sides are 21 it hints that we are looking at an equilateral triangle, which means two of its angles will be the same
By using the linear function which models the data in the given table, the cost of a textbook with 402 pages is equal to $47.4478.
<h3>What is a scatter plot?</h3>
A scatter plot can be defined as a type of graph which is used for the graphical representation of the values of two variables, with the resulting points showing any association (correlation) between the data set.
<h3>What is a linear function?</h3>
A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.
By critically observing the graph (see attachment) which models the data in the given table, we can infer and logically deduce that the linear function is given by:
y = 0.1057x + 4.9564
If x = 402, then y is given by:
y = 0.1057(402) + 4.9564
y = 42.4914 + 4.9564
y = $47.4478.

Answer:
5x + 20 + (-20) = 5x
Step-by-step explanation:
Opposite of 20 is just -(20) which is -20.
5x + 20 + (-20) = 5x + 20 -20 = 5x
