Because if you divide 34 by 2 you get 17. Then subtract 17 minus 5 which equals 12 so you multiply 12 times 2 for Janos' age and 12 times 3 for David's age which makes 60 but not 61. Their present age is 17.

Answer: 21 degrees
Step-by-step explanation:
In the evening, the temperature is 28 degrees and by midnight it has dropped 31 degrees lower, the temperature by midnight will be:
= 28° - 31°
= -3°
Between midnight and 4 am it goes down 6 more degrees. The temperature by 4am will be:
= -3° - 6°
= -9°
Then, by 9 am, the temperature goes up 30 degrees, the temperature at 9 am will then be:
= -9° + 30°
= 21°
Hi there!
We can use right-triangle trigonometry to solve.
We are given the HYPOTENUSE and ADJACENT sides, so we must use cosine in this instance.
cosθ = Adjacent/Hypotenuse
We can plug in what is given:
cos(28) = A/17
Solve for 'A':
17cos(28) = <u>15.01 ft</u>
