If (angle)A and (angle)B are supplementary, and m(angle)A = 57°, what is m(angle)B?

Sedbober [7]

Answer:

123°

Step-by-step explanation:

Supplementary angles add up to be 180 degrees.

This means angles A and B will add up to be 180 degrees.

We can find the measure of angle B by subtracting 57 from 180

180 - 57

= 123

So, the measure of angle B is 123 degrees

In your own words, describe how to graph the linear equation y = -1/5x + 3. Step by step

Gemiola [76]

Answer:

Steps given below and graph is attached.

Step-by-step explanation:

First Step:

Find out $y-intercept$ by substituting $x=0$

$y=-\frac{1}{5}\times 0+3\\\\y=3\\\\Hence\ line\ passes\ through\ (0,3).$

Second Step:

Find out $x-intercept$ by substituting $y=0.$

$0=-\frac{1}{5}x+3\\\\\frac{1}{5}x=3\\\\x=15\\\\Hence\ line\ passes\ through\ (15,0).$

Third Step:

Draw a line passing through $(0,3)\ and\ (15,0)$ .

Graph is attached.
