The question is illustrated with the attached image.
From the image, we have:
This gives:
--- approximated
156 and (14y+30) are opposite angles so they are the same. You can use this information to put them into an equation to solve;
14y+30 = 156
You want you the the y's alone, so you subtract 30 from each side.
14y = 126
Then divide each side by 14 to get what just 1 y is.
y = 9
Then to find what the other pair of opposite angle add up to subtract 156x2 from 360
156x2 = 312 360-312 = 48
Halve 48 to get the sum of just one of the opposite angles
48/2 = 24
Now you know that 3x = 24. Solve this equation
x = 8
It would be 57 minutes. Also love the Kenma profile picture!!
EXPLANATION: so 4:48 is almost an hr to 5:45. Just subtract 3minutes from an hr and you have your answer!
Answer: 7
Step-by-step explanation:
First set up your equation 40+21x=187
Subtract 40 from each side 187-40=147 40-40=0 Bring down your 21x than divide 147 by 21. 147÷21=7
