What is the value of b?

A.6
B.2sqr 13
C.3sqr13
D.3sqr14

En este caso 70 ° y 20 ° son complementarios porque 70° + 20° = 90°.

Más ejemplos podrían ser 47° y 43°, ya que 47° + 43° = 90°, 30° y 60°, 45° y 45° , etc.

Dos ángulos son suplementarios si su suma forma un ángulo llano, es decir, 180°.

10x

step-by-step explanation:

the greatest common factor 30 and 20 is 10

5 is a common factor of 30 and 20 but 10 is also a factor and 10 is greater than 5 so 5 will definitely not be apart of our answer

now the most amount of x's you factor our is just 1 factor of 1

so 10x the gcf of the terms in the polynomial

answer: a
