Angles a and b are complementary angles symmetry of angle a is 28° more than the measure of angle b find the missing angle measu

scoray [572]

Answer:

31 , 59

Step-by-step explanation:

a = b +28

a + b = 90 {Complementary}

b + 28 + b = 90 {Combine like terms}

2b + 28 = 90 {Subtract 28 form both sides}

2b = 90 - 28

2b = 62 {Divide both sides by 2}

b = 62/2

b = 31

a = 31 + 28

a = 59

A bag contains 25 balls 20 of which are blue what percentage of balls are not blue

Artist 52 [7]

Answer:

20%

Step-by-step explanation:

20/25 = blue

This means 5/25 of the balls in the bag are NOT blue

(25-20 = 5)

We need to convert 5/25 to a percentage

$\dfrac{5}{25} = \dfrac{5\times4}{25\times4}=\dfrac{20}{100}$

% = per cent

"per" means "out of"

"cent" means "one hundred"

20/100 = 20%
