The following are the temperatures in °C for the first 14 days of January: 7, -4.5, -2, 0, 2.5, 1, -5, -0.5, 3, -5.5, 4, 2, -3, 4.5 What is the median temperature for those 14 days? Give your answer as a decimal.

the first one

step-by-step explanation:

just id the test.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

prime
