Since a supplementary angle is 180 degrees do:
180 - 77
= 103 degrees
Answer: x= 19.5
(4x+12) = 90
Step-by-step explanation:
Notice the denoted right angle at the very top left. This means those intersecting lines are perpendicular forming 90 degree angles. All right angles are equal in measure so all 4 angles at the top are 90 degrees. We can then use corresponding angles to know that all of the bottom 4 angles are also 90 degrees. Now we can solve for x. (4x+12) =90. 4x= 78. X= 19.5
The answer is an equilateral triangle
Answer: He can play 4 rounds of his favorite game
Step-by-step explanation:
Zack has 3/4 hours to play video games. This means that he cannot spend more than 3/4 hours playing video games. it takes him 1/12hours to set up the system before he starts playing. This means that the time left for him to play games would be the time he has to play - the time it takes him to set up the video game. It becomes
3/4 - 1/12 = 8/12
If each round of his favorite game takes 1/6 hours, the number of rounds he can play would be the time he has left to play/time per round of his favorite game. It becomes
8/12 ÷ 1/6
= 8/12 × 6/1
= 4
-162
Because 9 x 2 = 18
18 - 180 = -162
