If G is the centroid of triangle ACE, AG = 8, GF = 7, BG = 5, find each measure.
1 answer:
Answer:
GD = 4
AD = 12
CG = 14
GE = 10
BE = 15
Explanation:
Because G is the centroid, then the following are correct
CG : GF = 2 : 1
AG : GD = 2 : 1
GE : BG = 2 : 1
So to find
GD, given AG = 8, we have:
8/GD = 2/1
GD = 8/2 = 4
AD = AG + GD
= 8 + 4
= 12
CG/GF = 2/1
CG/7 = 2/1
CG = 14
GE/BG = 2/1
GE/5 = 2/1
GE = 10
BE = GE + BG
= 10 + 5
= 15

Answer:
∠CAB = 48.81 degree.
Step-by-step explanation:
Let us consider, ∠CAB = ![\alpha](https://tex.z-dn.net/?f=%5Calpha)
From figure,
![tan \alpha = \frac{BC}{CA} \\tan\alpha = \frac{8}{7} \\ \alpha = tan^{-1} (\frac{8}{7} )\\\alpha = 48.81 degree](https://tex.z-dn.net/?f=tan%20%5Calpha%20%20%3D%20%5Cfrac%7BBC%7D%7BCA%7D%20%5C%5Ctan%5Calpha%20%20%3D%20%5Cfrac%7B8%7D%7B7%7D%20%5C%5C%20%20%20%20%20%20%20%20%20%20%20%5Calpha%20%20%3D%20tan%5E%7B-1%7D%20%28%5Cfrac%7B8%7D%7B7%7D%20%29%5C%5C%5Calpha%20%20%3D%2048.81%20degree)
To solve this you need to plug in -15 for x
y=2(-15)-3
y=-30-3
y=-33
I hope I've helped!
15 i think is this a question
