140 degrees because an angle of a circle is 360 degrees and you can subtract these angles from it to get 140 degrees
Plug any number in for x and find the resulting y, then if you need to graph place the coordinate points on the plane. For example if you set x=2 the equation becomes y=0.5(2). From here we can see 0.5(2)=1 and this is equal to 1 so in a data chart you would write under x the number 1 and under y the number 2.
The sum of 4.35 and -5.66
It shouldn’t be any longer vertically so that should be your answer
156°
D is a 24° angle, and is placed in a 90° angle, so 90-24=66
C is a right angle, so 90+66=156°
Hope this helped!
