An angle measures 20.6° less than the measure of its complementary angle. What is the measure of each angle?

IrinaVladis [17]

Answer:34.7 55.3

Step-by-step explanation: Complementery angles mean that they add to 90 degrees so we can repersent that in the equation x=(90-x)-20.6 first lets add like terms x=69.4-x (nice) now lets add x to each side 2x=69.4 now to get rid of the two lets divide by 2 on each side x=34.7. The angle that is 20.6 degrees less than its complementary angle has been found, to find the other angle add 20.6 degrees to the one we just found.

Choose the equations that will correctly solve this system. The sum of two numbers is 6. The difference of these same numbers is

Ulleksa [173]

X-y = -10 (the difference of these same numers is -10)

x+y = 6 (the sum of two numbers is 6)

x = 6-y
6-y-y= -10
-2y = -16

y = 8
x = -2
