A right angled triangle can be formed from the given scenario as shown below in the figure:
We have a perpendicular(opposite side), the measure of angle and we are interested in finding the hypotenuse.
sine of the angle relates its perpendicular side to hypotenuse as:
sin(x) = perpendicular/hypotenuse
⇒
Hypotenuse = Perpendicular/sin(x) = 13/sin(70) = 13.8 feet
This means, the length of the ladder is 13.8 feet, rounded to nearest tenth.
Answer:
785 cm³
Step-by-step explanation:
3.14x5x5x10=785
Since volume is the amount of space inside a object that is <u><em>3D</em></u><u /> you need to use cubic units also represented by the cubed exponent. This is because in square units your seeing how much space is in a square, or circle, or something that's <em><u>2D</u></em>, you get it? Whatever the dimension is that's what the exponent of the unit will be, so like a volume of a cube is 125 m^3 because it's 3d.
Answer:
√9
Step-by-step explanation:
√9 because 3×3 =9
and the sum of the number 3+3=6
3 is the number
