Which statements about angles are true? Check all that apply.

Mathematics
1 answer:
Vadim26 [7]3 years ago
8 0

Answer:

A,C,D,E

Step-by-step explanation:

The first one is true because in fact, supplementary angles' measures add up to 180°.

The second one is false because there are 5 types, not 3. These are the types:

acute angle-an angle between 0 and 90 degrees.

right angle-an 90 degree angle.

obtuse angle-an angle between 90 and 180 degrees.

straight angle-a 180 degree angle.

reflex angle- a angle between 180 and 360 degrees.

Third is true too because linear pair means two angles that form a straight line, or 180°.

Fourth is true because straight Angle theorem states that all the straight angles are 180 degrees. If the legs are pointing exactly in the opposite directions, then it forms a straight angle.

Last one is true because by definition complementary angles always form a right angle, which is 90°.

Hope it helps!

On a coordinate plane, a point is at (negative 4, negative 4) and (negative 4, negative 10).
Valentin [98]

Answer:

Option C.

Step-by-step explanation:

Hey there!

The points are; (-4,-4) and (-4,-10).

<u>Use </u><u>distance</u><u> formula</u><u>.</u>

d =  \sqrt{ {(x2 - x1)}^{2} +  {(y2 - y1)}^{2}  }

~ Put all values.

d =  \sqrt{ {( - 4 + 4)}^{2}  + (  { - 10  + 4)}^{2} }

~ Simplify it.

d =  \sqrt{ {0}^{2} + ( { - 6)}^{2}  }

d =  \sqrt{36}

Therefore, distance between the points is 6 units.

Answer:

8π in

64π mm²

Step-by-step explanation:

The circumference of a circle is equal to 2πr, where r is the radius.

2π(4) = 8π ≈ 25.132

The area of a circle is equal to πr²

π(8)² = 64π ≈ 201.062
