Answer:
7
Step-by-step explanation:
The centroid divides the median in a 2:1 ratio. Therefore,
AD = 2DM
x + 3 = 2(2x - 1) Remove parentheses
x + 3 = 4x – 2 Add 2 to each side
x + 5 = 4x Subtract x from each side
3x = 5 Divide each side by 3
x = ⁵/₃
AM = AD + DM
= (x + 3) + (2x – 1)
= 3x + 2 Substitute the value of x
= 3 × ⁵/₃ + 2
= 5 + 2
= 7
Length of median AM = 7.

The answer is the first option.
Answer:
x = 7, y = 24
Step-by-step explanation:
23x -16 + 8x - 21 = 180 because they are supplementary angles
31x - 37 = 180
31x = 217
x = 7
23(7)-16 = 7y - 23 because they are vertical angles
168 = 7y
y = 24
Answer:
19.8 cm
Step-by-step explanation:
Using the Pythagorean theorem , the Square of the distance between the top of the piece and the Shadow Is the sum of the height of the piece. and the lenght of the shadow. basically Just build a triangle with the 3 points you are given: height of the piece, lenght of the shadow and distance between the 2. so it's sqrt(13^2+15^2) = sqrt(394) =19.8 cm
