Answer:
total length of trip = 340km
u have done 260km
Step-by-step explanation:
you've already done 13/17 of the trip so 1-13/17=4/17 of the trip left
4/17 of the trip = 80km
total length of trip = 80*17/4 = 340km
u have done 340 - 80 = 260km
Answer:
200√3
Step-by-step explanation:
The triangle given here is a special right triangle, one with angles measuring 30-60-90 degrees. The rule for triangles like these are that the side opposite the 30° angle can be considered x, and the side opposite the 60° angle is x√3, while the hypotenuse, or side opposite the right angle, is 2x. All we need to know here are the two legs to find the area.
Since b is opposite the 30° angle, it is x, while side RS is opposite the 60° angle, meaning it is equal to x√3, meaning that the area of the triangle is 1/2*x*x√3. We can substitute in 20 for x, making our area 1/2*20*20√3. Multiplying we get 10*20√3, or 200√3.
