,cosB=

⇒sinA=sin30°,cosB=cos60°

⇒A=30°,B=60°

∴A+B=30°+60°=90°

Hence, the answer is 90°.

Answer 2

Answer:-

let the measure of the supplement be x

Then, the angle=x-32

According to question,

(x-32) +x=180[sum of the angles is 180°]

supplementary angles is 180°

=2x-32=180

=2x=180-32

=2x=148

=x148/2

=x=74

measure of the angle=x-32=(74-32)°=42°
