2.
The 21 degree angle shown is a corresponding angle to angle 3, which means they are identical, so angle 3 is 21 degrees.
Angle 3 and 4 are supplementary angles which need to add up to 180 degrees.
Angle 4 = 180 - 21 = 159 degrees.
3. A bisector means both sides are the same length.
Set the two equations to equal to solve for x:
4x+12 = 2x +18
Subtract 2x from both sides:
2x +12 = 18
Subtract 12 from both sides:
2x = 6
Divide both sides by 2:
x = 3
Now you have x, solve both equations and add them together:
4(3) +12 = 12+12 = 24
2(3) +18 = 6+18 = 24
24 +24 = 48
AB = 48
Answer:
X=50 hope this helps:)
Step-by-step explanation:
90+110=200
360-200=160
160=3x+10
150=3x
X=50
Answer:
11/18
Step-by-step explanation:
1/9 + 1/3 + 1/6
Adjust fractions based on the LCM,
2/18 + 6/18 + 3/18
Apply the fraction rule,
(2 + 6 + 3)/18
Answer,
11/18
It would be $54.00..........................
First add the seconds you have 45 +5+10 seconds which equals 60 seconds or 1 minutes. Now add the minutes 9 + 7 + 12 minutes = 28 minutes then add that 1 minutes that you got from the seconds 28 + 1 minute = 29 minutes 7:40 + 20 minutes = 8:00 + 9 minutes = 8:09 am. So Marsha arrived to school at 8:09 am. Comment if you have any questions.
