Answer:
75 degrees and 105 degrees
Step-by-step explanation:
Supplementary angles are those angles that sum up to 180 degrees
So angle A + B = 180 or B = 180 - A
then A/B = 5/7
7A = 5B
7A = 5(180 - A)
7A = 900 - 5A
12A = 900
A = 75
then B = 180 - A = 180 - 75 = 105

Answer:
The answer is 5.5
Step-by-step explanation:
+11-1/2 = +×– = += 5.5
Well , its upside down...
<span>Because G is the centroid of the triangle, therefore
AG = 2GF
That is,
5x + 4 = 2(3x - 1)
5x + 4 = 6x - 2
4 + 2 = 6x - 5x
6 = x
Therefore
AG = 5*6 + 4 = 34
GF = 3*6 - 1 = 17
A.F = AG + GF = 34 + 17 = 51
