Question 663685: if angle A&B are complementary angles & angle B=(x=29),angle A=3x-3,what is angle A

You can put this solution on YOUR website!
recall: complementary angles add up to 90 degrees
A%2BB=90
B=(x=29),angle A=3x-3
I guess you made mistake with B=(x=29); I assume it should be B=%28x%2B29%29
if so, then
x%2B29%2B3x-3=90
26%2B4x=90
4x=90-26
4x=64
x=16

A=3x-3
A=3%2A16-3
A=48-3
highlight%28A=45%29

B=16%2B29
highlight%28B=45%29
but, in case you have highlight%28B=29%29 and A=3x-3, then
3x-3%2B29=90
3x%2B26=90
3x=90-26
highlight%283x=64%29


A=3x-3
A=64-3
highlight%28A=61%29
