The measure of a angle is 63. what is the measure of its supplement? will give brainliest answer. 15

27 degree

bcz,

complement means 90 degree

so angle A +angle B=90 degree

    63 degree+angle B=90degree

    angle B=90-63

    angle B=27 degree

hence it is 27degree

the answer would be 117 cause supplement angles mean two or more angles equaling 180 degrees
