Answer:
75°
Step-by-step explanation:
There are 180° in a triangle, so using the ratios and the 180° setup an equation. Solve for x.
5x + 9x + 10x = 180
24x = 180
24x/24 = 180/24
x = 7.5
To find the largest angle measure, use 10x since 10 is bigger than 5 and 9.
10x
10(7.5)
75°
<u>Answer-</u>

<u>Solution-</u>
From the attachment,
AD = AE, so FA is a median.
BD = BF, so BE is a median.
CF = CE, so DC is a median.
And G is the centroid.
From the properties of centroid, we know that
The centroid divides each median in a ratio of 2:1
So,







So, GB will be
units
