Help pls!! this is a presentation I’m doing in class and I NEED this completed rn, ASAP!!! . What I need is just the answers for
Diano4ka-milaya [45]

15. 70° because a right angle is 90° and we have the angle of ADB which is 20°. So 90°-20°=70°.

16. 70° because angle PSQ is 60° and angle QSR is 10°. So 60°+10°=70°.

17. 55° because it says it in the explanation. I assume this is a typo and they meant to ask the measurement of ADC and in that case it would be 130° because angle ADB is 75° and angle BDC is 55°. 75°+55°=130°.

18. 40° because angle PSQ is a right angle which means it's 90°. So 130°-90°=40°.

19. 140° because angle ADB is 120° and angle BDC is 20° so 120°+20°=140°.

20. 125° because again it's in the explanation. But if it's a typo and they meant what is the measurement of PSQ then it is 50° because PSR is 125° and QSR is 75° so 125°-75°=50°.

Hope this helps! :)

Which equation does not represent this line?
WARRIOR [948]

when you get this kind of exercise, you just need to check which equations resemble the graph

A. y= 6-4x

y= -4x+6

B. y= -4x+8-2

y= -4x+6

C. y= -4x-8-1

y= -4x-9

D. y= -4x+6

-> A, B and D are the same equations

-> the easiest way to find which graph is correct (A/B/D OR C), is to create the graph yourself using the drawn graph:

y= ax+b

a= negative (the line goes down)

to find the a you go 1 step to the left and look which point of the graph has the same x. in this exercise it's when y=4

a=-4

b= the y-coordinate of the point where the graph cuts the y-axis.

b=6

-> graph shown in picture is y= -4x+b

-> graph A/B/D is correct

-> C is does not represent this line
