Answer:

Option 4.∠ERT and ∠MRC

Step-by-step explanation:

Definition of vertical angles  : The angles opposite each other when two lines cross. They are always equal.Vertical" refers to the vertex (where they cross).They are also called vertically opposite angles.

Option 1. ∠KRC and ∠CRH

Refer the figure .

These angles does not satisfy the definition of vertical angles . since these angles are not opposite.

Option 2. ∠KRE and ∠ERT

These angles does not satisfy the definition of vertical angles . since these angles are not opposite.

Option 3. ∠MRC and ∠KRM

These angles does not satisfy the definition of vertical angles . since these angles are not opposite.

Option 4.∠ERT and ∠MRC

MT and EC are the two lines that cross each other at vertex R ,

Thus ∠ERT and ∠MRC are opposite to each other .

Hence ∠ERT and ∠MRC are pair of vertcal angles .

There were 296296 tickets purchased for a major league baseball game. The general admissiongeneral admission tickets cost ​$6.50
VMariaS [17]

Answer:

The general admission ticket number is 160 and the upper box ticket number is 136

Step-by-step explanation:

In this case we can solve it using a 2x2 system of equations, like this:

let x be general admission tickets number

let y be upper box tickets  number

So:

6.5 * x + 10 * y = 2400

x + y = 296 => x = 296 - y

Replacing, we are left with that:

6.5 * (296 - y) + 10 * y = 2400

1924 - 6.5 * y + 10 * y = 2400

10 * y - 6.5 * y = 2400 - 1924

3.5 * y = 476

y = 476 / 3.5

y = 136

Now to calculate x:

x = 296 - 136

x = 160

The general admission ticket number is 160 and the upper box ticket number is 136

20 points <br><br> What do you remember about types of angles?
Allushta [10]

An acute angle is one that measures LESS than 90˚

An obtuse angle is one that measures between 90˚ and 180˚

A reflex angle is an angle that measures between 180˚ and 360˚

There are other many types of angles such as alternate angles and corresponding angles, but those 3 are the main ones.
