Answer:
∠ 2 = 104°
Step-by-step explanation:
- 8x - 48 = 9x + 275 [ alternate angles are equal ]
-8x - 9x = 275 + 48
-17x = 323
x = -19
9x + 275 = 9 × -19 + 275
= - 171 + 275
= 104°
∠ 2 = ( 9x + 275 ) [vertically opposite angles ]
∠ 2 = 104°
We will use the Cosine rule ( graph is in the attachment ):
c - the displacement
Angle: 90° + 45° = 135°
c² = a² + b² - 2 ab cos 135°
c² = 98² + 225² - 2 · 98 · 225 · ( -0.7071 )
c² = 9,604 + 50,625 + 31,183.11
c² = 91,412.11
c = √ 91,412.11
c = 302.344 km
Answer:
Step-by-step explanation:
This problem is solved using the linear function formula:
Where:
y= total bill
x= number of hours worked
b=fee
We have to find "a" in order to have the complete equation. We know that the constant fee (b) is 12$, and that if the hours worked are of 2.5 the total bill is $95.75, so we supplant on the equation and isolate "a".
So now we have the complete equation:
