Which set of angles are vertical angles?

∠1=∠4

∠3=∠2

∠5=∠8

∠6=∠7

Step-by-step explanation:

By definition:

- The angles that are opposite when a two lines intersect each other are called vertical angles.

- Vertical angles are congruent.

Keeping the information above on mind, the set of angles that are vertical are:

∠1 and ∠4 (∠1=∠4)

∠3 and ∠2 (∠3=∠2)

∠5 and ∠8 (∠5=∠8)

∠6 and ∠7 (∠6=∠7)

There are 4 set of vertical angles.

Step-by-step explanation:

The angles which are opposite by two traversal are called vertical angles.Vertically opposite angles are equal.

From the figure we can see that, a and b are two parallel lines and a traversal is given.

List of vertical angles.

1). < 1 and < 4  [<1 = <4]

2). <2 and <3  [ <2 = <3]

3). <5 and <8 [<5 = <8]

4). <6 and <7   [<6 = <7]

54

step-by-step explanation:

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
