The measure of angle 8 is 88 degrees
Answer:
x = 88
Step-by-step explanation:
The sum of the angles in a triangle add to 180
47+45 +x = 180
Combine like terms
92+x = 180
Subtract 92 from each side
92+x-92= 180-92
x =88
Answer:
I believe the answer may be x= 24.5 I'm not certain though
Step-by-step explanation:
The angles inside the triangle must all add up to 180 so we can subtract 80 from 180 to get 98. Now I'm assuming the two undefined angles are equal because of the two angle bisectors that create the second triangle. If I'm correct in assuming that them we can divided 98 by 2 to get 49 which would be the measurement of both bottom angles. Since there's a line bisecting both of them we would then cut that number in half to get 24.5. I hope this helped, I'm not fully certain of this answer though.
Answer:
Nolan's time is 100 seconds.
Step-by-step explanation:
Kong took 85 seconds.
Nolan took x seconds.
Kong took 15% fewer seconds than Nolan, so Kong's time is 85% of Nolan's time.
Kong's time is
85% of x or 0.85x
Kong's time is 85 seconds
0.85x = 85
x = 85/0.85
x = 100
Nolan's time is 100 seconds.
Answer:
About 5 hr 10 min
Step-by-step explanation:
rate 1 = 1 pool / 9 hrs rate 2 = 1 pool / 12 hours
now find the time with both rates combined
1 pool / ( 1/9 + 1/12) = 1/ (7/36) = 36/7 hr = 5 1/7 hr = 5 hr 8.6 min
