Answer:
x = 32
Step-by-step explanation:
Three angles have been shown in the figure which are located at a point of a straight line.
By the property of angles on a straight line,
Sum of the angles shown = 180°
(3x - 20)° + 30°+ (2x + 10)° = 180°
(3x + 2x) + ( -20 + 30 + 10) = 180
5x + 20 = 180
5x = 180 - 20
5x = 160
x =
x = 32
Therefore, x = 32 will be the answer.

Given function :
We need to identify a " initial amount", b "growth factor", r " rate of growth".
We know, exponential growth formula
, where a is initial amount, b is growth factor. On comparing with given function let us find values of a and b.
⇔
.
We can see a= 1.05 and b = 1.46.
Now, b=1+r.
Therefore, 1+r =1.46.
Subtracting 1 from both sides, we get
1+r-1 =1.46-1
r = 0.46.
On converting 0.46 into percentage, we get
0.46 × 100 = 46.
Therefore, intial amount a = a= 1.05 , growth factor b = 1.46, and the rate of growth r= 46%.
