Check all the equations that apply to meet the Segment AdditionPostulate in segment OQ. OP=6X+5,PQ=4x and OQ=45

Answers

Answer:

Options (2) and (5)

Step-by-step explanation:

Given in the question,

Length of OQ = 45

OP = (6x + 5)

PQ = 4x

By segment addition postulate,

Length of a segment OQ = length of segment OP + length of segment PQ

45 = 6x + 5 + 4x

10x + 5 = 45

10x = 45 - 5

10x = 40

x = $(40)/(10)$

x = 4

Therefore, Option (2) and Option (5) are the correct options.

there are 16 people at a party. they want to set up a relay teams with exactly 3 people each. can they do it ? explain

Answers

No, because 16 is not divisible by 3. 16 divided by 3 equals to 5 with a remainder of 1. Therefore, it is not possible.

Hope this helped ! (:

they can have 5 relay teams of three but everyone at the party cannot compete at the same time because 16 is not divisible by three

A triangle has an exterior angle with a measure of 120°. Can you determine the measures of the interior angles? Explain.

Answers

Measures of the interior angles will be found as below.

What are Interior Angles and Exterior Angles of a Triangle?

Interior angles of a triangle is the three angles formed inside the triangle by its sides.

Exterior angles of a triangle is the three angles formed by extending the sides

Given that triangle has an exterior angle with a measure of 120°.

Let a, b and c be the interior angles of the given triangle.

The sum of the exterior angle and the corresponding interior angle is 180°.

Let a be the corresponding interior angle.

a + 120 = 180

a = 180 - 120

a = 60°

One of the interior angles is 60°.

Sum of the interior angles of a triangle is 180°.

Then a + b + c = 180

b + c = 120

If the triangle is equilateral, then all the angles will be 60°.

If it is right angle, angles will be 30° and 60°.

Hence the interior angles can be found as above.

#SPJ2

If the exterior angle is 120 degrees, you subtract 120 degrees from 360 degrees (the two angles form a circle) and get 240 degrees.
This is not a possible angle for a triangle because the angles in a triangle always add up to 180 degrees. Also, angles in triangles can’t be more than 180 degrees

The question that I'm having issues with is, "The complement of an angle, A, in degrees, is equal to one-sixth of the supplement of the angle, also in degrees. Then A= "I know the answer is 72 degrees, but I don't know how to figure the problem out!

Answers

'Complement' = difference between an angle an 90 degrees.

'Supplement' = difference between an angle and 180 degrees.

Complement of A = 90 - A

Supplement of A = 180 - A

The problem says that the complement is 1/6 of the supplement, right ?

So 90 - A = (1/6) x (180 - A)

Multiply each side of this equation by 6 :

540 - 6 A = 180 - A

Subtract 180 from each side:

360 - 6 A = - A

Add 6A to each side :

360 = 5 A

Divide each side by 5 :

A = 72°

$90-A=(180-A)/(6)\n 540-6A=180-A\n 5A=360\n A=72$
