Answer:
Step-by-step explanation:
A median is a line that joins the angle vertex to the the point that is located at 1/2 the distance across the the line.
Where the medians meet is the centroid.
The centroid divides the median into a ratio of 2 to 1.
HM/ML = 2/1
ML = 20
HM / 20 = 2/1 Multiply both sides by 20
HM = 2 * 20
HM = 40
Answer:
X=14.4
Step-by-step explanation:
The equation for this problem is (a)(x)=b^2. So substituting the equation,
(10)(x)=(12)^2. Isolating x, we get x=14.4. to check our answer we solve the equation. (10)(14.4)=(12)^2 --> 144=12^2 --> 144=144. The statement is true.
(4 minus x) is the correct one.
The incorrect rounding for 53.864 is 53.87
