Question

I NEED HELP PLEASEEEE :) thank you!

Answer 1

Answer:

40

Step-by-step explanation:

The equation a^2 + b^2 = c^2 applies. 41 is c, 9 is b. When plugged in, you get  this:

a^2 +81 = 1681

When you subtract 81 from both sides, you get a^2 = 1600. The square root of 1600 is 40.

Answer 2

Answer:

x = 40

Step-by-step explanation:

The angle between the tangent and the radius at the point of contact is right, that is

Δ ABC is right with hypotenuse AC

Using Pythagoras' identity, then

x² + 9² = 41²

x² + 81 = 1681 ( subtract 81 from both sides )

x² = 1600 ( take the square root of both sides )

x = $\sqrt{1600}$ = 40
