angle a and angle b are complementary angles. If angle a is six more than three times angle b. What are the measures of the angles?

Question

anonymous · Answer

b=43.5
a=136.5

anonymous · Answer

let a=6+3b
complementary = total angles is 90

a+b=90
(6+3b)+b=90
6+3b+b=90
6+4b=90
4b=90-6
4b=84
b=21

90-21=69

angle a = 69
angle b = 21

no no!!!
a+b=180!
