(File attached) Find the value of each indicated angle. This is transversals.

Answers

Answer:

1: 136, 2: 55. 3: 53, 4: 70, 5: 61, 6: 112

Step-by-step explanation:

The value of x for each indicated angle are 136, 55, 53, 70, 61, and 112.

What are corresponding angles?

The angles that are in the same position on a given two parallel lines intersected by a transversal line are called the corresponding angles.

Corresponding angles are always equal.

We can also have alternate angles which are always equal.

We can also have alternate interior and exterior angles which are equal.

The angles on the same side make upto 180 degrees

We have,

x and 136 are alternate angles.

So,

x = 136

125 and x make a straight angle.

So,

125 + x = 180

x = 180 - 125

x = 55

53 and x are corresponding angles.

So,

x = 53

x and 110 are exterior angles on the same side.

This means,

x + 110 = 180

x = 180 - 110

x = 70

x and 61 are opposite angles.

This means,

x = 61

x and 112 are alternate exterior angles.

So,

x = 112

Thus,

The value of x is 136, 55, 53, 70, 61, and 112.

To pass her test, Tori needs to answer at least 65% of the questions correct. If there were 60
questions and she got 42 correct, did she pass? All work MUST be shown to justify your
answer.

Answers

1) change 65% to a decimal = .65

2) .65 • 60 = 37.2 questions need to be right

3) since she got 42 correct, that is greater than 37.2, so she passed.

OR

1) 42/60 = 0.7

2) 0.7 to a percent = 70%

3) since she got a 70% on the test, she passed.

Step-by-step explanation:

To obtain score of 80% on entire exam means the student have to answer

(80/100)×80 = 64 correct answers

Student have already answered 75% of the first 60 questions correctly meaning

(75/100)×60=45 correct answers from first 60 questions

Remaining correct answers s/he have to answer

64-45=19

So from remaining 20 questions s/he have to answer 19 correct questions that is

20 × (x/100) = 19

x = 19 ×(100/20)

x = 95%
