18. 105 = 2x - 11 —> 116 = 2x —> x = 58

Plug in x — > 2(58) - 11 —> 116 - 11 —> 105

105 + 105 = 210

360 which is the sum of all of the angles

360 - 210 = 150

Now divide 150 by 2 because those 2 angles and vertical angles and they should have the same degrees.

150/2 = 75

Angle AEB = 75 degrees

Angle CED = 75 degrees

Angle BEC = 105 degrees

19. (6x + 19) + x = 180 because they are adjacencies angles and make a straight line which equals 180 degrees

7x + 19 = 180 —> 7x = 161 —> x = 23

Now plug in x —> x = 23 for angle BEC

6(23) + 19 —> 138 + 19 —> 157

Angle BEC = 23 Degrees

Angle AEB =105 Degrees

Angle AED = 23 Degrees

Angle CED = 157 Degrees

Please help!!!!!!! im so confused lol

Answer:

a : c = 7 : 10

Step-by-step explanation:

The two ratios (a : b and b : c) both have b in common, so to work out what a : c is, we can use b to 'bridge' the two ratios together.

However, in a : b, b is 4. But in b : c, b is 2. We need to make sure b is the same in both ratios before we can combine the ratios together. The easiest way to do this is to multiply b : c by 2 to get b : c = 4 : 10. Now b is 4 in both ratios.

So now, we can combine the two ratios together to get a : b : c = 7 : 4 : 10. Since we only want a : c though, we can just drop the b and get a : c = 7 : 10. No simplifying is necessary since the ratio is already in its simplest form.

Hope that helps! :)

Answer:

1806 seats.

Step-by-step explanation:

From the question given above, the following data were obtained:

Row 1 = 24 seats

Row 2 = 27 seats

Row 3 = 30 seats

Total roll = 28

Total number of seat =?

From the above data, we can liken the roll to be in arithmetic progress.

Also, we are asked to determine the total number of seats in the theater.

Thus the sum of the sequence can be written as:

Roll 1 + Roll 2 + Roll 3 +... + Roll 28 i.e

24 + 27 + 30 +...

Thus, we can obtain obtained the total number of seats in the theater by applying the sum of arithmetic progress formula. This can be obtained as follow:

First term (a) = 24

Common difference (d) = 2nd term – 1st term

Common difference (d) = 27 – 24 = 3

Number of term (n) = 28

Sum of the 28th term (S₂₈) =?

Sₙ = n/2 [2a + (n –1)d]

S₂₈ = 28/2 [2×24 + (28 –1)3]

S₂₈ = 14 [48 + 27×3]

S₂₈ = 14 [48 + 81]

S₂₈ = 14 [129]

S₂₈ = 1806

Thus, the number of seats in the theater is 1806.
