Math (Medal)

OpenStudy (anonymous):

Yes?

OpenStudy (anonymous):

I'll get right on it! :)

OpenStudy (dayakar):

sum any two angles = 90 then they are called complement angles example 20 and 70

OpenStudy (dayakar):

sum of any two angles =180 then they are supplementary 130 and 50

OpenStudy (anonymous):

Okay, to answer 2 we must understand what complimentary and supplementary angles mean. Simply, they mean that they add up to either 90 or 180 degrees respectively. A would be the correct answer, I'll spare you the math :P Seeing what I just said, C is the answer to 3. Check my work yourself, and good luck!

OpenStudy (peachy1):

thankyou

OpenStudy (anonymous):

They are correct. You guys did a great job on this one. :) To find the complement, SUBTRACT 90 from 47. To find the supplement, SUBTRACT 180 from 47. And if you have been paying attention, number two should be very easy.

@JupitersRing01 @dayakar

OpenStudy (anonymous):

For which one? @Peachy1

OpenStudy (peachy1):

1

OpenStudy (anonymous):

No, try again... To find the complement we subtract 90 and 47 WHAT IS 90 - 47?

OpenStudy (anonymous):

Yes. What is 180 - 47?

OpenStudy (peachy1):

133

OpenStudy (anonymous):

So answer is what? Supplementary = 133 Complemetary = 43

OpenStudy (peachy1):

c

OpenStudy (anonymous):

Close...but not quite...complementary is 43 not 53. :)

OpenStudy (peachy1):

for number 2 is c?

OpenStudy (peachy1):

for number 1 its b

OpenStudy (anonymous):

No, do number 1 again. Number 2 is C, good job on that one

OpenStudy (peachy1):

ok

OpenStudy (anonymous):

{COMPLEMENTARY} 90 - 47 = ? {SUPPLEMENTARY} 180 - 47 = ? There you go.

OpenStudy (peachy1):

complement 133 suplement 43

OpenStudy (anonymous):

Let me try this another way... You are correct, just switch those answer. Complement is 43, and Supplement is 133. REMEMBER supplement is 180 - whatever number REMEMBER complement is 90 - whatever number in this case the number is 47. So... SUPPLEMENT is 180 - 47 COMPLEMENT is 90 - 47 So what is the answer now?

OpenStudy (anonymous):

@Peachy1

OpenStudy (peachy1):

133-43

OpenStudy (anonymous):

Supplement is...what?

OpenStudy (peachy1):

@DIDITHEDAD

OpenStudy (peachy1):

@MissSmartiez

OpenStudy (anonymous):

You still need help? Complement is 90 - 47. do that right now. WHAT IS 90 - 47

OpenStudy (anonymous):

Now solve for the supplement WHAT IS 180 - 47

OpenStudy (peachy1):

133

OpenStudy (anonymous):

And you are done. Complement is 43, supplement is 133. answer is A.

OpenStudy (anonymous):

Understand it now?

OpenStudy (peachy1):

yes

Great!
