Answer:
3.24 years
Step-by-step explanation:
We know that for the truck to become half of the value it has to decrease by %50 if it decreases by %15.4 the real question is 50/15.4=3.24 years because how many years will it take for %15.4 to pile up and eventually become %50
Answer:
x = 30°
Step-by-step explanation:
The tangent and secant from a point outside the circle combined with the radius form a triangle.
The sum of the 3 angles in the triangle = 180°
The angle at the centre of the circle = 60° ( equilateral triangle )
The angle between the tangent and the radius on the circle = 90°, thus
x = 180° - (90 + 60)° = 180° - 150° = 30°
