Answer:
x = 19.9
Step-by-step explanation:
Given the above right angled triangle, we can find the missing side, x, using the trigonometric ratio formula.
The given angle (θ) = 19°
The adjacent length = x
Hypotenuse length = 21
Thus,
Cos (θ) = adjacent/hypotenuse
Multiply both sides by 21 to solve for x

Answer: OPTION B
Step-by-step explanation:
Let's call:
c: the number of cars.
m: the number of motorcycles.
Based on the given information, you can set up the following system of equations:
You can solve it by the Elimination method:
- Multiply the first equation by -4.
- Add both equations to cancel out the variable "c".
- Solve for "m":
(24 motorcycles)
- Substitute m=24 into any of the original equations ans solve for "c". Then:
(14 cars)
