a2) 25

a3) 45

Step-by-step explanation:

all triangle equal to 180

Answer:

65

25

45

Step-by-step explanation:

1) green triangle 180 - 50 - 65 = 130 - 65 = 65

2) purple triangle 180 - 130 - 25 = 50 - 25 = 25

3) red triangle 180 - 45 - 90 = 90 - 45 = 45

Complete Question

If the measurement of a central angle is 5pi/6, find the length of its intercepted arc in a circle with a radius of 15 inches

a 33.4 inches

b. 35.6 inches

C. 37.5 inches

d. 39.3 inches

Answer:

d. 39.3 inches

Step-by-step explanation:

We are to find the Arc length of the circle

To solve the above question, the formula is given as:

Arc length = Central angle × radius

From the above Question, we are given:

Central angle = 5pi/6 = 5π/6

Radius = 15 inches

Hence,

Arc length = 5π/6 × 15 inches

Arc length = 235.61944901923448/ 6

Arc length = 39.26990817 inches

Approximately , the Arc length

= 39.3 inches.

Therefore, Option d is the correct answer.

Answer:

Step-by-step explanation:

Total Weight = 2½ + 1⅓ + 2

= 5/2 + 4/3 + 2

= 15/6 + 8/6 + 12/6

= 35/6

= 5⅚ pounds

Answer:155

Step-by-step explanation:

because they are parallel lines. If the angles differed even by 1°, eventually the lines would meet, therefore they would not be parallel.

Answer:

Firstly angle 6 and 2 are equal because of corresponding angles

so 6 = 2

Now angle 1 + 2 = 180 ( linear pair)

angle 1 = 180 - 55

1 = 125

Answer:

D. (2, -1)

Step-by-step explanation:

I took the test and got it right.

Triangle QRS is rotated 180° about the origin. On a coordinate plane, triangle Q R S has points (-4, 1), (-4, 4), (2, 1). So, the coordinates of point S will be (2, -1).

Let the point be having coordinates (x,y).

If the point is in first quadrant:

Subcase: Clockwise rotation:

Then (x,y) → (y, -x)

Subcase: Counterclockwise rotation:

Then (x,y) → (-y, x)

If the point is in the second quadrant:

Subcase: Clockwise rotation:

Then (x,y) → (y, -x)

Subcase: Counterclockwise rotation:

Then (x,y) → (-y, x)

Triangle QRS is rotated 180° about the origin.

On a coordinate plane, triangle Q R S has points (-4, 1), (-4, 4), (2, 1).

So, the coordinates of point S will be (2, -1).

Answer:

The distance between point R and point Z is 7 blocks below.

Step-by-step explanation:

The question says the distance between Point r and Point Z. R to Z is going down. You start at R and find Z. When you have done that, You count the number of blocks or spaces that they have in between the space. And when you have counted you get your answer. The answer is never a negative number always positve even if the point is has a negative number with posivte or a negivate  with negative or a postive wwith a postive.

Step-by-step explanation:

divide the numbers

Given:

A chess club with 45 members is electing a new president.

Bob received 18 votes.

To find:

The percentage of the club members who voted for Bob.

Solution:

We have,

Total number of members = 45

Votes received by bob = 18

Now, the percentage of the club members who voted for Bob is

[tex]\%=\dfrac{\text{Number of members voted for bob}}{\text{Total members}}\times 100[/tex]

[tex]\%=\dfrac{18}{45}\times 100[/tex]

[tex]\%=\dfrac{2}{5}\times 100[/tex]

[tex]\%=\dfrac{200}{5}[/tex]

[tex]\%=40[/tex]

Therefore, 40% of the club members voted for Bob.

Answer:

£15000

Step-by-step explanation:

Lucy, Mary and Nora's father leaves them an inheritance in the

ratio 5: 3:2. Mary gets £4500, How much was there in total?

Giving the ratio of inheritance 5:3:2

5+3+2 = 10

Mary's ratio = 3

Marys share = £4500

Total share x can be gotten as thus

3/10 × x = 4500

3x/10 = 4500

3x = 45000

x = 45000/3

x = 15000

Hence £15000 was there in total

Answer:

C. 3/4

Step-by-step explanation:

Using the SOH CAH TOA identity;

tan theta = opposite/adjacent

From the diagram

Opposite = x

Adjacent = 12

tan <B  = x/12

Since cot <B = 1/tan <B

cot <B = 12/x

Get x using pythagoras theorem

x² = 20²-12²

x² = 400 -144

x² = 256

x = 16

Hence cot <B = 12/16

cot <B =3/4
