In the diagram of circle C, what is the measure of <1?
17°
35°
70°
71°

Given:

Measure of one arc 106°

Measure of another arc 36°.

To find:

The measure of ∠1

Solution:

If two secants intersects outside a circle, then the measure of the angle formed is one-half the positive difference of the measures of the intercepted arcs.

The measure of angle 1 is 35°.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
