Answer:
Radius = 7
Step-by-step explanation:
Since BA is tangent to circle O, it creates a 90° angle with the radius
Therefore, you can use Pythagorean theorem to solve this problem
a² + b² = c²
Let's say a is the radius
b is 5
c is 8.6
a² + 5² = 8.6²
a² + 25 = 73.96
Subtract 25 from both sides
a² = 48.96
Root both sides
a ≈ 6.997142274
Answer:
WELL I DONT SEE THE PICTUE BUT WHATS THE PROBLEM?
Step-by-step explanation:
Answer:
x = 15
Step-by-step explanation:
Given
2 = -
+
x
Multiply through by 4 to clear the fractions
8 = - 7 + x ( add 7 to both sides )
15 = x
Answer:you multiply the decimal by the number behind the decimal
