I Need To Know How To Find The Measure Of Angle A.

Answers

Answer 1

Answer:

90°

Step-by-step explanation:

We need expressions for the measures of the three interior angles. Then we add them and set the sum equal to 180. Then we solve for x. Finally, we use the value of x in x + 100 to find the measure of angle A.

Let's first find an expression for each angle.

Angle A: m<A = x + 100

Bottom left angle: The interior angle is vertical to the angle measuring x + 60, so the interior angle also measures x + 60.

Bottom right angle: Let's call the measure of the interior angle y. y and the angle measuring 140° are supplementary, so y + 140 = 180; y = 40.

Now that we have expressions for the three interior angle measures, we add them and set the equal to 180.

(x + 100) + (x + 60) + 40 = 180

x + 100 + x + 60 + 40 = 180

2x + 200 = 180

2x = -20

x = -10

The measure of angle A is x + 100, and x = -10

m<A = x + 100 = -10 + 100 = 90

Answer: 90°

UWV is a 30°-60°-90° triangle.

The sides of a 30°-60°-90° triangle are in the ratio 1:√3:2

The length of the side opposite the 90° angle is 10,

so the length of the side opposite the 30° angle is 5

Step-by-step explanation:

The probability the teacher that chooses a girl to write the date on the board is :

C) 3 sevenths.

Given:

Boys =12

Girls =9

Total number of students = 12 + 9 = 25.

So the probability of choosing a girl is = n(girl) / n(all students) = [tex]\frac{9}{25}[/tex]

This is close to 3 sevenths.

no because you wouldn't switch the fraction upside down to make it opposite.

Answer:

What Doug probably means to say is that the reciprocal of -2/5 is 5/-2. So, by this definition, Doug would be correct. However, you would not usually call it the "opposite" of a number, rather, the reciprocal.

The numbers are reciprocals of the other as their product is equal to one "-2/5 * 5/-2 = 1"

Answer:

1. Vertical angles. X = 128º

2. The two angles labeled make up a linear pair & are supplementary, meaning they add up to 180º.

So:

7x + (x+20) = 180

Solve for x:

7x + (x + [20-20]) = 180 - 20

7x + (1)x = 160

8x = 160

X = 20

3. The two angles are complementary, meaning they add up to 90º.

So:

X + 35 = 90

Solve for x:

X + (35-35) = 90 - 35

X = 55

4. the two angles are complementary, and add up to 90º.

So:

4x + 2x = 90

Solve for x:

6x = 90

6x/6 = 90/6

X = 15.

5. Vertical angles, so they are equal in measure.

So:

75 = 4x - 25

Solve for x:

75 + 25 = 4x (-25 + 25)

100 = 4x

100/4 = 4x/4

X = 25.

6. The 3 angles all add up to 180º. they are supplementary.

So:

75 + x + (3x + 5) = 180

Solve for x:

(75 - 75) + x + (3x + 5) = 180 - 75

X + (3x + 5) = 105

X + 3x + (5-5) = 105 - 5

(1) x + 3x = 100

4x = 100

4x/4 = 100

X = 25

7. The 2 angles shown in the picture add up to 180º & are supplementary.

So:

x + (2x - 21) = 180

Solve for x:

X + (2x [-21 + 21]) = 180 - 21

(1)x + 2x = 159

3x = 159

3x/3 = 159/3

X = 53.

Sorry for the late response.

Find the equation of a line that passes through the point (0,4) and has a gradient of 2.
Leave your answer in the form y = mx + c

Answers

Answer:

y = 2x + 2

Step-by-step explanation:

y = mx+c

m = slope

c =y -intercept

Therefore, the required equation is:

y = 2x + c

Putting the point (0,4) in it as it lies on a line, we get:

4 = 2 + c

Therefore:

c = 2

So, y = 2x + 2

Answer:

ANGLE PQS = 45°

When a standard die is rolled, find the probability of getting a. 5 b. A number larger than 2 c. An odd number.

Answers

Answer:

P(getting a 5)=[tex]\frac{1}{6}[/tex]

P(number larger than 2)=[tex]\frac{2}{3}[/tex]

P(numbers which are odd) =[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

When a standard die is rolled, we get sample space as {1,2,3,4,5,6}

So, let's use formula

P(E)=[tex]\frac{outcomes favorable to event E}{Total number of outcomes}[/tex]

For part A:

Event is getting a 5.

So, out of 6 samples , we get one 5 as outcome

So,

P(getting a 5)=[tex]\frac{1}{6}[/tex]

For part B:

The numbers larger than 2 are {3,4,5,6}

So, p(number larger than 2)=[tex]\frac{4}{6} =\frac{2}{3}[/tex]

P(number larger than 2)=[tex]\frac{2}{3}[/tex]

For part C:

The numbers which are odd are {1,3,5}

So, p(numbers which are odd)=[tex]\frac{3}{6 } =\frac{1}{2}[/tex]

P(numbers which are odd) =[tex]\frac{1}{2}[/tex]

Answer:

21 quizzes

Step-by-step explanation:

What we know:

- Hayley takes 9 quizzes in 3 weeks

What we want to find:

- The number of quizzes Hayley would've taken after 7 weeks

We need to first find the number of quizzes Hayley would take in 1 week and then multiply that number by 7. To find the number of quizzes per week, divide 9 by 3:

9÷3=3

Therefore, every week, Hayley takes 3 quizzes.

Now, we multiply 3 by 7:

3×7=21

Therefore, after attending 7 weeks of school, Hayley would've taken 21 quizzes in total.
