Answer:
x = 62.3 degrees.
Step-by-step explanation:
We should notice a certain trigonometric function that works here.
tan x = opposite side / adjacent side
tan x = 40/ 21
x = arctan (40/21) = 62.3005 degrees
x = 62.3 degrees.
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
Use the sin identity to find that side. Sin(30) = a/12...12 sin(30) = a, and a = 6
Answer:
y=12
Step-by-step explanation:
Use order of operations. Subtract 18 from both sides and the divide by 2.
2y+18 -18=42-18
2y=24
y=12
