et mA = 40°. If B is a complement of A, and C is a supplement of B, find these measures. mB = ° mC = °

Free_Kalibri [48]

Alright, lets get started.

We have given angle A = 40°

We are also given angle B is complement of A.

Complementary angles are two angles whose sum is 90, it means

angle B = $90- A$

angle B = $90 - 40$

angle B = 50° Answer

Now given, angle C is supplement of angle B.

Supplementary angles are two angles whose sum is 180°.

Means angle C = $180 - B$

angle C = $180 - 50$

angle C = 130° : Answer

Means angle B = 50° and angle C = 130°

Hope it will help :)

Sylvia took three times in a video game she scored -120 points during her first turn 320 points in her second time and -80 point

sp2606 [1]

Her average score for the 3 turns is 40 because you have to add all of the scores so -80 and -120 is -200 so add that to 320 and you get 120 divide that by 3 because she took 3 turns and you get 40
