How do you know if a figure is similar or congruent?

my bad it it was D lol .....

Answer: 2 and -8

Step-by-step explanation:

Answer:

<1  and <6 = 98

<2 and <3 = 139

<4 and <5 = 123

Step-by-step explanation:

82 + 9x - 6 + 6x - 1 = 180

15x + 75 = 180

15x = 105

x = 7

<1:

x + 82 = 180

x = 98

<2:

6x - 1 = 6(7) - 1 = 41

x + 41 = 180

x = 139

<3 = <2 because of vertical angle thm so <3 = 139

<5:

9x - 6 = 9(7) - 6 = 57

x + 57 = 180

x = 123

<4 = 5 because of vertical angle thm

<6 = <1 because of vertical angle thm

Answer:

144 degrees

Step-by-step explanation:

work out the exterior angle of the shape 360/no of sides

then take it away from 180 (angle on a straight line) leaving you with the answer

The required measure of x would be 144 degrees for the shown figure.

An interior angle is defined as an angle produced on the inside of a polygon by extending the sides of the polygon.

Interior angles of a polygon = (sides - 2) × 180°

This diagram shows part of a regular 10-sided polygon.

As per the question,

10x = (10- 2) × 180°

10x = 8 × 180°

10x = 1,440°

x = 1,440°/10

Apply the division operation, and we get

x = 144°

Thus, the required measure of x would be 144 degrees.

Answer:

150 ft

Step-by-step explanation:

Apply pythagorean theorem to find length of hypotenuse, side c:

Pythagorean theorem is given as:

c² = a² + b²

a = 90 ft

b = 120 ft

c = hypotenuse

Plug in the values

c² = 90² + 120²

c² = 22,500

Take the square root of both sides

c = √22,500

c = 150 ft

Answer:

5 + (-3)

Step-by-step explanation:

there are 5 positives and 3 negatives

so when you add them together you get 5 + (-3)

Answer:

See below in bold.

Step-by-step explanation:

Let Anna's, Boris and Clara's numbers be a b and c.

a + 20 = b - 22 + 21

b - 20 =  c + 22 + 21

a + 20 = b - 1

b - 20 = c + 43

a  - b  + 20 = -1      

Adding the last 2 equations:

a  = c + 42

c = a - 42

So Clara's number is 42 less then Anna's number.

Answer:

5:7

Step-by-step explanation:

First you have to find the watermelons owned by the three of them.

Let's take Susan as 'x'

According to the question:

1. Alex has twice the watermelons as Susan -> 2x

2. Amy has 6 more watermelons than Susan -> x+6

The sum of the watermelons is 66

SO,

x + 2x + x + 6 = 66

4x = 60

x = 15

Susan has 15

Alex has 30

and Amy has 21

Now  we do the ratio:

Susan : Amy

15    :   21

5     :    7

From the attached cone:

[tex]r = 5[/tex] -- radius

[tex]l = 9[/tex] --- slant height
