Answer:
As radius is perpendicular to tangent,
By pythagoras theorem :
x² = (x + 9)² - 15²
x² = x² + 18x + 81 - 225
18x = 207
x = 11.5
Answer:
Answer:
30 degrees
Step-by-step explanation:
We know that the angle is going to be half of the minor arc it encompasses.
Since the minor arc is 60 degrees, the angle is 30 degrees!
That's the same as 1.024 ÷ 10⁴
Each time we divide by 10 we move the decimal point one place to the left. If we have to we add zeros at the front.
1.024 ÷ 10⁴ = 0.1024 ÷ 10³ = 0.01024 ÷ 10² = 0.001024 ÷ 10 = 0.0001024
Answer: 0.0001024
