Question

Name a pair of complementary angles. (1 point)

angle sign1 and angle sign4
angle sign1 and angle sign2
angle sign3 and angle sign4
angle sign1 and angle sign6

2.
If mangle sign1 = 37°, what is the measure of angle sign4? (1 point)

53°
43°
37°
27°

3.
If mangle sign1 = 40°, what is the measure of 5? (1 point)

50°
40°
35°
25°

Answer 1

what's the definition of complementary angles? That they add up to 90 degrees.

Which of these pairs adds up to 90 degrees?

Answer 2

number 3

Answer 3

No. Angle 3 looks like a right angle all by itself, doesn't it. So that can't be right.

Answer 4

yeah my bad so 40 and 50 =90?

Answer 5

You mean in question number 3? Yes, if angle1 = 40 degrees, then angle5 = 50 degrees

Answer 6

yes

Answer 7

are we on question 1?

Answer 8

I thought you were just answering question number 3 because you gave specific angles.

One question #1, which of those pairs add up to 90 degrees?

angle sign1 and angle sign4 : no, these angles are the same and unless we are told then are both 45 degrees, then we can't know they add up to 90 degrrees

angle sign1 and angle sign2: Looks good to me!

angle sign3 and angle sign4: Angle 3 is already 90 degrees

angle sign1 and angle sign6: Angle 6 is already 90 degrees

Answer 9

so the answer for 1 is Angle sign and 2

Answer 10

Yes.

You now tell me what you think the answer is to question 2 and why
2.
If mangle sign1 = 37°, what is the measure of angle sign4? (1 point)

53°
43°
37°
27°

Answer 11

how can i find the answer to this question?

Answer 12

this is my first time doing this

Answer 13

Angles opposite of two intersecting straight lines are equal.

Answer 14

ok

Answer 15

In your diagram, AB and CD are two intersecting straight lines.

Now are angles 1 and 4 opposite? Yes.

And therefore must they be equal? Yes.

Hence if
angle1 = 37 degrees

then necessarily
angle4 = ...... what?

Answer 16

27?

Answer 17

Are angles 1 and 4 equal? Yes. So if angle1 = 37, angle4 cannot possible equal 27

Answer 18

37?

Answer 19

Yes! 37 = 37

Answer 20

You figure out question 3 by yourself. You now have all the information you need to do it.

Answer 21

lol.
