The answer is D, because point slope form is y-y1=m (x-x1)
The average rate of your heart beat is about 80 times per minute.
Therefore 80 x 1440(minutes per day) = is 115,200
Therefore you heart beats about 115,200 per day.
Answer: The range = 41.
Step-by-step explanation:
97 - 56 = 41
Answer: 90° , 60° and 30° .
Step-by-step explanation:
Given : In a right triangle with a leg of 4 units and a hypotenuse of 8 units.
One angle should be 90°. (A right triangle has a 90° angle.)
Let the given leg is the side opposite to the angle in the triangle.
Then by trigonometry , we have
[Sine of an angle is the ration of the side opposite to the angle and the hypotenuse of a right triangle.]
Also ,
Let x be the measure of the third angle.
BY Angle sum property of triangle , we have
Therefore , the measures of all angles in the triangle : 90° , 60° and 30° .
