The percent decrease: 25%

The percent decrease: 33.33..%

So, B is the correct statement

15% = 0.15

249 x 0.15 = $37.35 ( amount of discount)

249 - 37.35 = $211.65 ( sale price )

Alright, lets get started.

We have given angle A = 40°

We are also given angle B is complement of A.

Complementary angles are two angles whose sum is 90, it means

angle B =

angle B =

**angle B = 50° Answer**

Now given, angle C is supplement of angle B.

Supplementary angles are two angles whose sum is 180°.

Means angle C =

angle C =

**angle C = 130° : Answer**

**Means angle B = 50° and angle C = 130° **
