Answer:

Part 1:

Angle DCB is a right angle.

So, angle DCA + angle ACB = 90

Angle ACB = 90 - angle DCA = 90-50=40

Answer is option C. 40

===========================

Part 2:

Angle DCB is a right angle.

So, angle DCA + angle ACB = 90

Angle ACB = 90 - angle DCA = 90-60=30

Whats the answer I DONT het how to do this At all

DENIUS [597]

Given that the radius r of a circle is written as a function of the area A with the following equation:

$r=\sqrt[]{\frac{A}{\pi}}$

The domain of the above function is the area A of the circle.

This is because, in this context, the area is an independent and unique variable.

A is the input value.
