The 2 angles form a linear pair and angles that form a linear pair have a sum of 180 so
10x + 15 + 5x = 180
15 + 15x = 180
180 - 15 = 15x
165 = 15x
11 = x
Answer:
14: 104.5 square inches
15: 706.5 square inches
Step-by-step explanation:
14: 19x11= 209
209/2= 104.5 square inches
15: formula: pi times the radius squared
15x15= 225
225x3.14= 706.5 square inches

Answer:
30 seats
Step-by-step explanation:
To answer this question, we will be assigning values for both rows and seats.
R = Rows
S = Seats
Remember that rs = 600
r = s - 10, plug this equation into rs = 600, and factor it:
s(s-10) = 600
s^2-10s-600 = 0
(x-30)(x+20) = 0
There are 30 seats in the row. To determine which one is your answer, your answer MUST be positive because it is impossible to have negative seats. (x-30) is 30, which is the positive value found when factoring.
C). 6*6√2*12 is your answer.... i think
