Supplementary means 2 angles adding up to 180 or the line of AEF in this case

so supplementary pairs like DEH and HEF would add up to 180, same with DEJ and JEF

Answer:

Angle DEH and angle HEJ and HEK and KEF add up to 180 degrees

Step-by-step explanation:

Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees. ... For example, a 50-degree angle and a 40-degree angle are complementary; a 60-degree angle and a 120-degree angle are supplementary.

Write the equation of the line in slope-intercept form using y=mx+b​

Answers

Answer:

y = 1/2x+2

Step-by-step explanation:

First find the slope using y1-y2 over x2-x1 picking two points, the two I am using are (0,2) and (2,3). Once I use the formula, the slope is 1/2. The Y intercept (b) is where the line intersects it. (0,2) You know it is the y intercept because the x coordinate is 0. So the final equation would be y=(slope)x+ (y-int) so FINAL ANSWER: y=1/2x+2

Which of the following angles can be added together to create 177°? Explain your answer using words.

Answers

First you’d look for ones units that add up to 7, so in this case (5)4 and (6)3

Add 54 and 63 to get 117

Subtract 117 from 177 to get 60

25 and 35 equal 60 (I just know that from common knowledge I have no idea how to explain that in words)

So 25 + 35 + 54 + 63 = 177

A. 525 in squared

Step-by-step explanation:

Fundamentally, the area of a parellelogram such as this can be calculated the same way the area of a normal rectangle is calculated: Length x Width.

Thus,

(27 + 8) x 15 = Area

35 x 15 = Area

525 = Area

Don't forget your units! (Inches squared)

Answer: The answer is 525
