O is the centroid. Find the value of x. (Sorry if u cant see the photo :/, but this is Geometry btw)
klemol [59]

Answer: x = 6

==============================================

Explanation:

The medians of a triangle meet up at the centroid in such a way that they cut each other at a ratio of 2:1, meaning that one part of the median is twice as long as the other. In this case, MO is two times longer than OP, so,

OP = 2*MO

and

MP = MO + OP

MP = MO + 2*MO .... replace OP with 2*MO

MP = 3*MO

9x-24 = 3*(x+4) ... plug in the given expressions

9x-24 = 3x+12

9x-3x = 12+24

6x = 36

x = 36/6

x = 6

True or False: Given the illustration below, the value of y is 100º
sladkih [1.3K]

we are given

we know that

sum of all angles in any quadrilateral is 360

so, we can write it as

y+120+85+53=360

now, we can combine it

y+258=360

now, we can subtract both sides 258

y+258-258=360-258

y=102

so, this is FALSE..........Answer
