in the diagram triangle BCD is mathematically similar to triangle ACE

Answer:

Divide 360 by the difference of the angle and 180 degrees. For example, 360 divided by 15 equals 24, which is the number of sides of the polygon. Divide 360 by the amount of the exterior angle to also find the number of sides of the polygon.

Answer:

45 degrees

Step-by-step explanation:

Hi there!

We're given that one of the triangle's exterior angles is 90 degrees. Using that, we can solve for the corresponding interior angle by subtracting 90 from 180 degrees:

180-90 = 90

Given that the two legs of this right triangle are of equal length, we know that the remaining two angles both measure x. Knowing that the sum of the interior angles in a triangle is 180 degrees, we can set up an equation:

x+x+90=180

2x=90

x=45

Therefore, x is 45 degrees.

In fact, any right triangle with legs of equal length will be a 45-45-90 triangle, meaning the other two angles measure 45 degrees.

I hope this helps!

Answer:

x = 60

y = 60

Step-by-step explanation:

To find y (y and 120 are supplementary angles):

y + 120 = 180

y = 180 - 120

y = 60

x = y (because of corresponding angles)

x = 60

43.4

Answer:

112 cm (red, 4)

Step-by-step explanation:

length = b

width = a

b = 7a

42 = b - a

42 = 7a - a

42 = 6a

a = 7          => b = 7a       b = 7*7 = 49

Perimeter = 2*(a+b)

= 2*(7+49)

= 2*(56)

= 112 cm

Answer:

x = 11

Step-by-step explanation:

These angles are alternate exterior angles which means they are equal to each other:

5x + 9 = 6x - 2

5x - 6x = -2 - 9

-x = -11

x = 11

Answer:

Sides = 8 each and base = 6

Step-by-step explanation:

Let congruent legs = x, then the base is x - 2 so,

P = x + x + (x - 2)

22 = 3x - 2

24 = 3x

8 = x (sides)

base = 8 - 2 = 6

Answer:

The domain of y = cos θ is all real numbers. This is because any real number can be plugged in for θ and y will be equal to a real number. This can be shown graphically because the y = cos θ will go on infinitely both to the right and left.

Answer:

30

Step-by-step explanation:

x = original number of stamps

x+23  (added 23 stamps to the collection)

3(x+23)  tripled in number

3(x+23) = 159

Divide each side by 3

3(x+23)/3 = 159/3

x+23=53

Subtract 23 from each side

x+23-23 = 53-23

x = 30

Answer:

t ≥ 0.2c

Step-by-step explanation:

Her tip is at least 20% of the cost of the meal, so her tip is greater than or equal to 20% of the cost of the meal

tip ≥ 20% of the cost of the meal

t ≥ 20% of c

Another way of writing "20% of c" is multiplying the two values, so we have

20% of c = 20% * c

t ≥ 20% * c

To convert from a percentage to a decimal, we can divide the percentage by 100. Here, we have

20% = 0.2

t ≥ 0.2 * c

Answer:

x = 4

Step-by-step explanation:

Vertical angles are equal.

m∠1 = m∠2

10x - 9 = 4x + 15

Add 9 to both sides

10x = 4x + 15 + 9

10x = 4x + 24

Subtract 4x from both sides

10x -4x = 24

6x = 24

Divide both sides by 6

x = 24/6

x = 4
