Find the value for the missing side length. Round to the nearest tenth if necessary.

1 answer:

7 0

20 is adjacent to the angle. x is opposite. Therefore you want to use tangent because that is what you are given.
tan(72)=x/20
multiply the denominator:20•tan(72)=x/20•20
20•tan(72)
Answer=61.5
Rounded=62

Whats the table for y=-4|x-5|+3 <br>how to solve absolute value function with a table and graph

zepelin [54]

Answer:

For a table for x and y values for this absolute value equation, it would look like this:

x --- y

3 --- (-5)

4 --- (-1)

5 --- 3

6 --- (-1)

7 --- (-5)

Step-by-step explanation:

When you are building a table for an absolute value graph, you start with the base formula for absolute value equations:

y = a|x-h| + k

In this equation (h, k) is the vertex and therefore the middle point. From there we go two numbers in each direction for our x values. And for every change in x, y changes by a factor of a.
