what is complex number??

Answer 1

Answer:

In mathematics, 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 symbol called the imaginary unit, and satisfying the equation i² = −1. Because no real number satisfies this equation, i was called an imaginary number by René Descartes.

Answer 2

Explanation:

Answer:

let the angle ZYQ =x;

angle PYQ=x

PYX is a straight line

angle PQY + angle QYZ+ angle XYZ=100°

→x+x+64°=180°

→2x+64°=180°

→ 2x= 180 -64°

→x=116°/2

→x=58°

♦ anglePYQ=58°

♦ angle QYZ=58°

→angleXYQ=angle XYZ+angleZYQ

→ angleXYQ =64°+58°

→angleXYQ=122°

Reflex angleQYP=360°- 58°

=302°

Therefore, answer = 58°,122°,

302°.
