Well...it says the sum of the angles measure 360...so lets set them equal to 360
40 + x - 10 + 1/3x + x - 20 = 360...combine like terms
2 1/3x + 10 = 360
7/3x = 360 - 10
7/3x = 350
x = 350/(7/3)
x = 350 * 3/7
x = 1050/7
x = 150 <=====
3 3/8 to the nearest whole number is 3 because 3/8 < 1/2
Li can expect to roll a one 4 times.
Since there are six possibilities (1, 2, 3, 4, 5 & 6), you divide 24 and 6 to get 4.
T=3s/10+2x/5 hope this helped <3
complement means the sum of the two angles equals 90°
32° 22min 44 sec + x = 90° 0min 0 sec
Note: 90° = 89° 59 min 60 sec
- <u> 32° 22min 44 sec </u>
57° 37min 16 sec
