(6x – 30° and m ZA and ZB are supplementary angles. If mZA
ZB (82 +28)º, then find the measure of ZA.

9514 1404 393

  48°

Step-by-step explanation:

Supplementary angles total 180°.

  m∠A +m∠B = 180°

  (6x -30)° +(8x +28)° = 180°

  14x = 182 . . . . . . . . . . . . . . . . divide by ° and add 2

  x = 13 . . . . . . . . . . . . . . . . . . . .divide by 14

Then the measure of angle A is ...

  m∠A = (6·13 -30)° = 6(13 -5)° = 6·8°

  m∠A = 48°

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

step-by-step explanation:

32.50-7.50=25

225/25=11
