Question

PLEASE HELP! I DON'T UNDERSTAND!


<1 and <2 are linear pair. m<1=x-30, and m<2=x+76. find the measure of each angle?

1) <1=67,<2=123
2)<1=37,<2=153
3)<1=37,<2=143
4)<1=67,<2=113

Answer 1

@karinahorses

A linear pair of angles are two adjacent angles whose exterior sides form a straight angle.

A straight angle has measure 180 degrees.

Answer 2

m<1 + m<2 = 180
x-30 + x+76 = 180

@karinahorses Solve the equation for x. Post what you get and we'll compare answers. Okay?

Then, we have to find the angle measures.

Answer 3

I have a very hard time with this stuff? I've never gotten it would it be 4? (or d)

Answer 4

well, tis understandable karinahorses

Answer 5

@karinahorses

I intended to followup with you on this problem earlier today when the OpenStudy site went down. So, let us continue now.

m<1 + m<2 = 180

x-30 + x+76 = 180

(Combine like terms on the left side of the equation)

2x + 46 = 180

(Subtract 46 from each side of the equation)

2x = 134

(Divide both sides by 2)

x = 67

Now, find the measures of angles 1 and 2

m<1=x-30 = 67 - 30 = ? @katrinahorses


and m<2=67+76 = ?

Note: When you get the measure of the two angles, check to see if they add to 180.

Answer 6

3)<1=37,<2=143 After a while I have found my answer THANK YOU SO MUCH!:)

Answer 7

I knew it was either 3 or 4 (C or D) and I read it and looked in my book to find out more about this certain question.

Answer 8

Alrighty. You are welcome. The textbook is always a good first resource when working problems, especially Geometry problems.

Answer 9

Lol I read it at first Just didn"t get it and being a quiz I was try not to resort to my book but I looked over all my answers and only got 1 other wrong with all 12 question and I totally guessed on that one:)
