Answer:
angle A=72 degrees and angle B= 108 degrees
Step-by-step explanation:
1. the sum of the angles altogether must be 360 degrees
2. the picture shows that the two horizontal lines are the same and that the two vertical lines are the same
3. that means that 3y+27=5y-3
4. solve for y
5. 3y+27=5y-3
6. 27+3+3y=5y
7. 30+3y=5y
8. 30=5y-3y
9.30= 2y
10. 15=y
11. Then solve what each angle is by plugging in y
12. 3(15)+27 and 5(15)-3
13. Remember, the two should equal the same number
14. 72 degrees and 72 degrees
15. 72+72=144
16. The two horizontal lines equal 144 together which means because the whole figure equals 360 degrees, 360-144= the two vertical lines
17. 360-144=216
18. 216 equals the two vertical lines sum put together and since the two lines are equal, we cut 216 in half
19. 216/2= 108
20. each vertical line equals 108 and each horizontal line equals 72 degrees
21. Therefore angle A=72 degrees and angle B= 108 degrees
22. I know this was a lot of info. and I hope I helped you understand it!
Answer:
722900
Step-by-step explanation:
You look at the ones place, and since it is 9, you make the 9 in the tens place a 0, and then regroup the one and add it to the 8 in the hundreds place. So your answer would be 722900
Answer:a
Step-by-step explanation:
just a guessing cause I don’t see nothin.
STEP 1:
Divide the length of the ribbon by the size of the pieces.
12 inches= 1 foot
= 9 ft ÷ 15 inch pieces
convert ft to inches
= (12)(9) ÷ 15
= 108 ÷ 15
= 7.2 pieces from one roll
STEP 2:
multiply the number of pieces that can be cut from one roll by the number of rolls
= 7.2 pieces * 5 rolls
= 36 pieces total from 5 rolls
ANSWER: The greatest number of 15-inch pieces that can be cut from five 9-foot rolls is 36.
Hope this helps! :)
