What are endpoints of a line segment that divides the triangle defined by the vertices (2, 2), (8, 0), and (8, 4) into two congr

Art [367]

Answer: Option 'B' is correct.

Step-by-step explanation:

Since we have given that

triangle defined by the vertices (2, 2), (8, 0), and (8, 4)

We need to divide the triangle into two congruent triangles.

As we know that "Median " divides into two congruent triangles.

So, we will apply the formula of "Mid point of two coordinates":

So, Suppose (2,2) and (8,0)

$(\frac{2+8}{2},\frac{2+0}{2})\\\\(\frac{10}{2},\frac{2}{2})\\\\=(5,1)$

Suppose (2,2) and (8,4)

$=(\frac{8+2}{2},\frac{2+4}{2})\\\\=\frac{10}{2},\frac{6}{2})\\\\=(5.3)$

Hence, Option 'B' is correct.

a bag contains 60 marbles, some blue and some green. the ratio of blue marbles to green ones is 1:5. how many blue marbles are t

olga55 [171]

Hello!

For every 1 blue marble there are 5 greens

You add the numbers in the ratio

1 + 5 = 6

Divide this number from the amount of marbles

60 / 6 = 10

Multiply the ratio by this

1 * 10 = 10

5 * 10 = 50

There are 10 blue marbles and 50 green ones

The answer is 10

Hope this helps!

Angle Q = 85° Determine angle O.

kkurt [141]

Answer:

∠O = 95°

Step-by-step explanation:

since ∠Q = 85°, arc NOP = 2(85°) = 170°

arc PQN = 360° - arc NOP

arc PQN = 360° - 170° = 190°

∠O = 1/2(arc PQN) = 1/2(190°) = 95°
