28 degrees. This is because the first angle is 12 degrees, the third is x degrees and the second is 5x. You know that in a triangle the angles add up to 180 degrees so 12 + 5x + x = 180. Then you get 6x =168 and x =28 degrees. (**x being the thrid angle**)
Ages of Dan and Cary are 29 and 33 respectively.
<u>Step-by-step explanation:</u>
Step 1:
Form equations out of the given details. Let the age of Dan be x, then age of Cary is x + 4.
In 7 years, sum of their ages = 76
⇒ (x + 7) + (x + 4 + 7) = 76
⇒ 2x + 18 = 76
⇒ 2x = 58
⇒ x = 29
Step 2:
Calculate age of Cary.
⇒ x + 4 = 33
If A = L x W. . . Then L = A/W
Answer:
1080
Step-by-step explanation:
Firstly, if he is paying 50 per month, we need to know the number of months it would take him to finish paying the money. Hence that would be 800/50 = 16 months
Now we know there is a surcharge of 17.5 for each month he owes a balance. The total balance he is to pay is thus 16 * 17.5 = 280
The total cost of the jacket is thus 800 + 280 = 1080
