<span>When a </span>radius<span> is drawn to a point of tangency, the </span>angle formed<span> is always a right angle.
Basically, the 2 tangents and the radii form a quadrilateral.
The 3 angles on the right are 90, 111 and 90 degrees.
Therefore, the fourth angle = 360 -90 -111 -90
Which equals 69 degrees.

Answer:
0.00094
Step-by-step explanation:
Scientific Notation is a shortened form of writing a number using exponents. It has the following rules:
- Use a positive exponent for large numbers greater than 1.
- Use a negative exponent for small numbers less than 1.
- Always write the first number as a value between 0 and 9.
9.4 x 10^-4 has a negative exponent and will be a number smaller than 1. This means 0.00094 and 0.0094 are options. Now count from the decimal in each to the space between 9 and 4. In the first it is 4. In the second it is 3. Since the exponent is -4, this means 0.00094 is the solution.
