These are SIMILAR figures. Fill in the missing values for the angles and sides

Answers

Answer:

75 62 22 30 65 18

Step-by-step explanation:

Given that the figures are similar figures, then:

x and y in the Parallelograms:

x = 88

y = 118°

x, y, and z in the Hexagons:

x = 164°

y = 36

z = 33

x, y, and z in the Triangles:

x = 10

y = 21

z = 75°

What are Similar Figures?

Similar figures have pairs of angles that have the same degree measure, and the ratio of their corresponding sides are equal.

Given that the pairs of figures are similar, let's find the missing angles and sides as shown below:

Find x and y in the Parallelograms:

x/66 = 100/75

Cross multiply

x = (100 × 66)/75

x = 88

y = 118° (opposite angles of a parallelogram are congruent)

Find x, y, and z in the Hexagons:

x = 164° (congruent angles)

y/54 = 20/30

y = 36

22/z = 20/30

z = 33

Find  x, y, and z in the Triangles:

x/15 = 12/18

x = 10

14/y = 12/18

y = 21

z = 180 - 65 - 40 = 75°

Please please find the area for this polygon!

Answers

Answer:

508

Step-by-step explanation:

28*16= 448

6*6= 36

4*6= 24

448+36+24= 508

In order to find the area of a polygon, all you have to do is follow the formula: area = 1/2 x perimeter c apothem. To sum it together, perimeter = the sum of the lengths of all the sides. So add 6, 16, 16, 6, 4, 6, 28, and 18! And then you have 100! Then multiply it by 1/2! So your answer should be 50. Please consider brainliest.

Kasey and Jordan are counting calories while eating lunch in the school cafeteria. in one week, Kasey had 10 slices of pizza and 5 cups of fruit salad. Jordan had 6 slices of pizza and 7 cups of fruit salad. Kasey’s calorie count was 3070 and Jordan’s was 2522. How many calories are in a slice of pizza?

Answers

Answer:

222 calories from the pizza

Step-by-step explanation:

nandhini123-

Given:

slices of pizza ate by Kasey =10

cups of fruit salad by Kasey=  5

slices of pizza ate by Jordan = 6

cups of fruit salad by Jordan=  7

Kasey's calorie  count = 3070

Jordan calorie  count = 2522

To Find:

calories Jordan got from pizza =?

Solution:

Let the calorie of one slice of pizza be  x

and the  calorie of one cup of fruit salad be  y

According to the question, the equation that represents the Kasey's Scenario is

10x + 5y = 3070-------------------------------------(1)

Similarly the equation that represents the Jordan Scenario is

6x + 7y = 2522--------------------------------------(2)

multiply eq(1) by 6 we get

60x + 30y = 18420---------------------------------(3)

multiply eq(2) by 10 we get,

60x + 70y = 25220----------------------------------(4)

Subtracting eq (3) from (4) we get

 60x + 70y = 25220

 60x + 30y = 18420

 (-)        (-)        (-)

-----------------------------------

0x + 40y = 6800

---------------------------------

=>40 y = 6800

=>y =

=> y = 170

So calorie of one cup fruit salad is = 170 calories

substituting the y values in eq 1 we get

10x + 5(170) = 3070

10x + 850 = 3070

10x = 3070 - 850

10x = 2220

x =

x= 222

So calorie of one pizza slice = 222 calories

Now we know that  Jordan ate 6 slices of pizza

calories  Jordan get from pizza = number of pizza he ate  X calore per pizza slice

=> 6 x 222

=>1332 calories

Step-by-step explanation:

1.

-3x - 5 = 16              add 5 to both sides

-3x = 21                    divide -3 to both sides

x = -7

2.

-4(y-2) = 12             distribute -4

-4y + 8 = 12             subtract 8 from both sides

-4y = 4                divide -4 to both sides

y = -1

Answer:

A(b + c) = 112

Step-by-step explanation: For this equation you rewrite the equation with the numbers in place of the variable. This would loook like 8(4 + 10). Next to follow pemdas we do parenthesis first, 4 + 10 = 14. Then you multiply 14 x 8 which is 112. I checked this on a calculator and on paper and both got the same answer.
