Answer:
60 & 55
Step-by-step explanation:
1. the sum of the angles 1; 2 and 3 is 180°, then
m∠1=m∠2=m∠3; ⇒m∠3=60°;
2. m∠3=m∠r; ⇒ m∠r=60°;
3. m∠α= 180-(m∠r+65°)°; ⇒ m∠α=55°

Answer:
The equation modelling the situation is .
After <u>10 months</u> the cost would be $400.
Step-by-step explanation:
Given:
Annual Fee of flying club = $200
Monthly fee = $20
We need to write an equation for total cost.
Solution:
Let the number of months be denoted 'm'
Let Total cost be denoted by 'T'
Now we can say that:
Total cost is equal to sum of Annual Fee of flying club plus Monthly fee multiplied by number of months.
framing in equation form we get;
Hence The equation modelling the situation is .
Now given:
We need to find the number of months when total cost will be $400
So we will substitute T= 400 in above equation.
Subtracting both side by 200 we get;
Dividing both side by 20 we get;
Hence After <u>10 months</u> the cost would be $400.
