The second option down, "nine times the difference of a number cubed and three", is the correct answer.
The answer would be 10 minutes. If you look at the highest point from distance and you go down to the time it lands on 10.
I hope this helps love! :)
The top angle inside the triangle would be 90-20 = 70 degrees
so X = 15 / tan(7) = 5.45 = 5.5 yd
The sum of the interior angles of a triangle is 180°.
Let's suppose that all 3 angles in the ratio are divisible by a value x.
So the three angles become 1x, 2x and 3x.
1x + 2x + 3x = 180°
6x = 180°
x = 30° [ By dividing both sides by 6 ]
Thus the three angles are: 1x = 30° ; 2x = 2*30 = 60° ; 3x = 3*x = 90°
Hence the smallest angle is 30°.
