Answer: x=40, y=70,
Step-by-step explanation:
To find angle x you first need to find O. You do this by subtract <u>180-40.</u> Then you would get <u>140.</u> Take this 140 and subtract it by 180. Your answer for x should be <u>40. </u>
To find angle y you first need to know that <u>x=40</u>. Taking this you would subtract it by <u>180</u>. It would leave you with <u>140</u>. Taking <u>140</u> your going to dive it in half to get y. Your answer for y should be <u>70.</u>
Sorry I'm not sure how to find z.
I believe that A is the answer. We can solve this by multiplying 75cm, 65cm and 30cm together. This would give us 146,250.00ml. We can then divide 146,250.00 by 1000 to receive 146.25. We then divide 146.25 by 2 to calculate how many litres there are in half a tank. This would result in 73.125. After that, we multiple 73.125 by the cost of the fuel, which is R20.35. We then receive R 1,480.09375, which can be rounded to R 1,480.10
Answer:
hello :
8(3/4a)−8 = 24/4a - 8 = 6/a -8 = (6-8a)/a
Your answer is n>17 hope this helps
