The pattern is +2 for the length, and the width stays the same. Hope this helped. :)
Answer:
332
Step-by-step explanation:
To find how many seats there were, multiply the number of rows with the number of seats in each row:
15 (24) = 360
From these total seats, there are 28 empty seats, meaning:
360 - 28 = 332
There were 332 people.
The inscribed angle theorem says that the measure of angle BDC is 2 times larger than the measure of angle BAC.
Angle CBD has measure 44 degrees, and we're told angles CBD and BCD are congruent. This means triangle BCD is isosceles.
The interior angle measures of any triangle add up to 180 degrees, so the measure of angle BDC must be

Then
.
(1/3x+3)=5-x
multiply both sides by three
1x+9=15-3x
add 3x to both sides
4x+9=15
subtract 9 from both sides
4x=3
divide both sides by 4 to isolate x
x=3/4
