Answer:

  • B. (3, 2)

Step-by-step explanation:

<u>Given vertices of triangle:</u>

  • A(1, 2), B(3, 4), C(5, 0)

<u>The centroid is found as the average of x- and y- coordinates of three vertices:</u>

  • C = ((x₁ + x₂ + x₃)/3, (y₁ + y₂ + y₃)/3)

<u>Substitute the coordinates into formula:</u>

  • C = ((1 + 3 + 5)/3, (2 + 4 + 0)/3) = (3, 2)

Correct choice is B

Find the measures of all of the angles.
irga5000 [103]

Answer:

a:

1. ABC = 60°

2. BCA = 90°

3. CAB = 30°

b:

XVR = WVS = 125°

RVS = 55°

RST = VSU = 110°

RSV = UST= 70°

TUS = 39°

Step-by-step explanation:

a:

According this is a Right Triangle ( BCA = 90°) and the sum angles of a triangle is 180° :

90+5x+9x+6=180

14x=84

x=6

Then we have : ABC = 9(6)+6 =60

CBA = 5(6)=30

b :

Given that the size of the opposite angles to a vertex are equal and the sum of the interior angles of a triangle is 180 degrees, the size of all angles can be easily found.
