Assuming you want us to write an equation.
2n-15=-27
17/8 = 2 1/8 U need to covert 2 3/4 to an improper fraction then covert it to 8ths which means you multiply the numerator and denominator by 2 and solve then simplify. :)
Answer:
Step-by-step explanation:
altitude rule
10 / x = x / 3
x^2 = 30
x = sqrt(30)
As M is a point of tangency, KN and MN are perpendicular.
Therefore : KN² = KM² + MN²
(radius + NP)² = radius² + 336²
(radius + 294)² = radius² + 336²
radius² + 2*294*radius + 294² = radius² + 336²
588radius = 336² - 294²
radius = 26460/588
radius = 45
Hope that clear and helpful
