Two angle are side to be compliment if there sum is 90°

<B + <A = 90°

<B = 90° - <A

<B = 90° - 40°

<B = 50°

Two angle are side to be compliment if there sum is 180°

<B + <C = 180°

<C = 180° - <B

<C = 180° - 50°

<C = 130°

m<B + m<C = 50° + 130° = 180°

kirza4 [7]

Answer:

qualitative

Step-by-step explanation:

Favorite rock group is the qualitative variable because it shows an attribute. It does not depict a quantity or numbers. The favorite rock group will perform and show their ability to deliver music articles so it is showing quality not quantity. It is an attribute.

Variable is defined as the characteristic being studied so it is a qualitative variable meaning it is showing quality of the characteristic.
