Which set of angle measures CANNOT be the angle measures inside of a triangle?

45°, 45°, 45°
60°, 75°, 35°
60.5°, 59.5, 59°
65°, 60°, 55°

Answers

Answer:

Therefore, option A,B and C cannot be the angles of triangles.

Step-by-step explanation:

Given that total angles in a triangle is 180° so you have to add up all the angles :

Option A,

45° + 45° + 45° = 135° (Not a triangle)

Option B,

60° + 75° + 35° = 170° (Not a triangle)

Option C,

60.5° + 59.5° + 59° = 179° (Not a triangle)

Option C,

65° + 60° + 55° = 180° (It is triangle)

Find the additive inverse of 3x−6

Answers

Answer:

3x+6

Step-by-step explanation:

inverse means the opposite of the sign and the opposite of subtraction is addition so I used addition

The additive inverse of 3x − 6 is -3x + 6

What is additive inverse?

The additive inverse of a number x is a number that when added to x gives a result of 0.

For the expression 3x - 6

The additive inverse is a number that can be added to the expression to get 0. Hence:

The additive inverse of 3x − 6 is -3x + 6

Answer:

They have no relation, except for the fact that they intersect. If the equations were instead y = +5/4x - 1/2 and y = -4/5x + 2, or y = +4/5 + 2 and y = -5/4x -1/2, then they would be perpendicular.

Option 3 is the right answer.

Step-by-step explanation:

For the given lines y = -4/5x+2 and y = -5/4x - 1/2

we have to identify whether lines are parallel or perpendicular.

As we know if two lines are perpendicular then gradients of two lines will in the form of

m1 m2=(-1)

and if the lines are parallel then the gradients of the lines will be same.

m1=m2

Here m1 = -4/5 and m2 = -5/4

Therefore

m1m2=(-4/5)(-5/4)=(+1)

and  

m1≠m2

So both the lines are neither parallel nor perpendicular to each other.

Option 3 is the right answer.
