For problems 8-10, find the measures of the unknown third angles.

8=58.5 9=125 10=55

Step-by-step explanation:

a triangle equals 180. so by add the angles we do know than subtracting the answer from 180. is our final answer

8=58.5°

9= 125°

10= 55°

Step-by-step explanation:

8.) 31.5 + 90 = 121.5 - 180 = 58.5°

9.) 25 + 30 = 55 - 180 = 125°

10.) 45 + 80 = 125 - 180 = 55°

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

step-by-step explanation:

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
