Question

angleA and angleB are complementary angles.
IF angleA = angleB-20", then find angleA and angleB.​

Answer 1

Answer:

Step-by-step explanation:

 so according to question

angle A + angle B =90                               (complementary )

angle A =90- angle B                                     ...........1

also given

angle A =angle B- 20                                   .............2

from 1 and 2

90-angle B=angle B-20                                       LHS of 1 and 2 are equal

70=2 angle B

Angle B =35                                     ............................3

from 1 and 3  

angle A is 55 .
