Given that S is the centroid of triangle MNO, find SQ.
DochEvi [55]

Answer:

First, we need to calculate for x. Since,

MP = PN

Thus,


3x-4 = x+4

2x = 8

x = 4


Next, we calculate for MS 

MS = 2x + 2 = 10


Since, MS = 2SQ

10 = 2SQ

Then,

SQ = 5 units


Therefore, the correct answer is B.

Use the figure to the right to find the missing lengths of the triangle.
pychu [463]

To find AB(x) and BC(y), you can do(there are multiple ways you can do this):

tan A = \frac{y}{7}

tan 60° = \frac{y}{7} or (tan 60°) · 7 = y

tan 60° = \frac{\frac{\sqrt{3} }{2} }{ \frac{1}{2} } = \sqrt{3}

√3 · 7 = y

7√3 cm = y


sin B = \frac{7}{x}

sin 30° = \frac{7}{x} or x= \frac{7}{sin 30}

sin 30° = \frac{\frac{1}{2} }{1} = \frac{1}{2}

x = \frac{7}{\frac{1}{2} } = 14

x = 14 cm


AB = 14cm

BC = 7√3 cm
