Answer:
x = 4
Step-by-step explanation:
co interior angles add up to 180.
this means that: 48 + 34x - 4 = 180
thus 48 + 34x = 184
therefore, 34x = 136
so, x = 4.
Answer:
radius = 6
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ←r is the radius
x² + y² = 36 ← is in this form
with r² = 36 ⇒ r = 
= 6
Answer:
Step-by-step explanation:
<u>Composite Function</u>
Given f(x) and g(x) as real functions, the composite function 
is defined as:
It can be found by substituting g into f.
We are given the functions:
f(x) = -x + 3
g(x) = -x -1

Answer:
Thus the last row has 119 seats.
The total number of seats in 24 rows = 1476
Step-by-step explanation:
The number of seats in each row make an arithmetic series. We will use arithmetic equation to find the number of seats in last row:
An = a1+ (n-1)d
An = 4+(24-1)5
An = 4 + (23)(5)
An = 4 + 115
An = 119
Thus the last row has 119 seats.
Now to find the sum of seats we will apply the formula:
Sn = n(a1 + an)/2
Sn = 24(4+119)/2
Sn = 24(123) /2
Sn = 1476 .....
The total number of seats in 24 rows = 1476....
