An angle measures 51 , what is the measure of its complement

complement of 51 is 39

supplement of 54 is 126

Step-by-step explanation:

Complementary angles add to 90 degrees

51 + c = 90

Subtract 51 from each side

51-51 + c = 90-51

c = 39

The complement is 31

Supplementary  angles add to 180 degrees

54 + s = 180

Subtract 54 from each side

54-54 + s = 180-54

s = 126

The supplement is 126

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
