Answer:
111°
Step-by-step explanation:
- All these are parallel lines, so the 36° angle is equal to the 36° angle inside the big triangle because they are vertically opposite.
- Ignore the line cutting between 45° and the 30° and consider it as one triangle
- Add them to get 75°
- Now you have two known angles 75° and 36°
- To get angle <em>x</em><em> </em>add 75° and 36° to get 111°
- Because x° is an exterior angle and exterior angles equal to the sum of interior angles opposite it inside the triangle.

Step-by-step explanation:
The probability of obtaining a head or tail in tossing a coin is modeled by the binomial distribution.
The probability of obtaining heads (success) is p = 1/2.
In n tosses, the expected statistical parameters are
m = np, the mean
σ = √[np(1-p)]
In 72 tosses of the coin, the standard deviation for the number of heads obtained is
σ = √[72*(0.5)*(0.5)]
= 4.243
Answer: 4.243
