Question

Find the measures of the complement and the supplement of an angle with a measure of 20 degree's.
A- complement, 150 degrees; supplement, 260 degree's.
B- complement, 340 degrees; supplement, 160 degrees
C- complement, 70 degrees; supplement, 160 degrees
D- complement, 160 degree's; supplement, 70 degrees.

Answer 1

Answer 2

complement is 90, so subtract 20 from 90, and supplement is 180, so subtract 20 from 180

Answer 3

Say if I have some angle x

Answer 4

so 70 and 160?

Answer 5

Now, I want to calculate its y and supplement is z.

So, x+y = 90 and x+z = 180

Answer 6

ok

Answer 7

can u help me out on that? lol

Answer 8

Now can you find out the answer.

Answer 9

Now, here you have, x = 20. Now, can you find out y and z ?

Answer 10

yes 70 and 160

Answer 11

@js7474 , did you get it ?

Answer 12

no not really?

Answer 13

Okay you have x = 20. Now I gave you two equations:

For complementary angle (let y) : x + y = 90

For supplementary angle (let z) x+z = 180

Answer 14

im really bad at this stuff

Answer 15

No problem

Answer 16

Can you tell me the problem you are facing ?

Answer 17

i have trouble figuring out x and y

Answer 18

Okay here x is the angle given for whose complementary angle and supplementary angle is asked to be calculated. So, here x = 20.

Now, y is the required complementary angle and z is the required supplementary angle.

Answer 19

Now can you tell me values of x, y and z ?

Answer 20

do u still need help b/c I have an easier way to explain it
