Okay I need ur help pls very urgent..

Answer 1

Supplementary angles are those which sum upto 180°

$\angle 1+\angle2=180^{\circ}$

Complementary are those which sum to 90°

$\angle 1+\angle2=90^{\circ}$

so if you know one angle, you can find other.

Answer 2

Answer:Look at my explaination

Step-by-step explanation:The complement of 50 is 90-50 giving us 40degrees

The supplement of 145 is 180-145=35 degrees

The compliment of 27 degrees is 90-27=63 degrees

The supplement of 50 degrees is 180-50=130 degrees
