Answer:
x=14
Step-by-step explanation:
8x-9+6x-7 = 180 (being adjacent angles)
14x-16 = 180
14x = 180+16
14x =196
x = 196/14
x =14

The centroid of a triangle divides the median of the triangle into 1 : 2
The measure of FQ is 18, while the measure of TQ is 6
Because point T is the centroid, then we have the following ratio

Where FT = 12.
Substitute 12 for FT in the above ratio

Express as fraction

Multiply both sides by 12

This gives

Divide 12 by 2

The measure of FQ is calculated using:

Substitute 12 for FT, and 6 for TQ

Add 12 and 6

Hence, the measure of FQ is 18, while the measure of TQ is 6
