Angle 4 would also be 135. the two on the top would add to 180, making a whole circle altogether that equals 360. so, you would do 180-135 = 45. angle 5 is 45. angle 7 would also be 135 because angle 4 and 7 are vertical angles.
y≤-2x +2
y< 1/3x +2
this is the answer to this
Answer:
Nine less than twice a number 2x-9
Seven divided by a number 7-x
Ninety-nine plus the difference of eleven and five 99+(11-5)
Four-fifths more than three times. Number 3x+4/5

Answer:
552.920307 yd^2 or 552.92 yd^2 for sigfigs
Step-by-step explanation:
basically you take the area of the entire circle and subtract the interior circle to leave the ring and that’s your answer
so the area formula of a circle is π r^2
the radius (r) is just half the diameter so the entire diameter is 48 so the radius is 24 - π(24)^2 = 1809.557368^2
then the interior circle’s diameter is 40 so the radius is 20 - π(20)^2 = 1256.637061^2
so now it’s just subtraction:
1809.557368 yd^2 - 1256.637061 yd^2 =
552.920307 yd^2 or 552.92 yd^2 for sigfigs
hope this helps :)
Try graphing it to help, but since it's not a slanted line (because the y-values are the same), you just do x1-x2:
-3 - -7 = 4
