OpenStudy (saifoo.khan):

Just a sec.

OpenStudy (saifoo.khan):

supplementary angles add upto 180*.

OpenStudy (anonymous):

yes

OpenStudy (saifoo.khan):

So, for the first one it's angle 4.

OpenStudy (saifoo.khan):

For question 2, it's asking for complimentary angle of angle 3. Complimentary agnles add upto 90* So, it's angle 2.

OpenStudy (saifoo.khan):

For question 3. Vertically opposite angles are equal of each other|dw:1348279518333:dw|

OpenStudy (saifoo.khan):

Therefore, 2 and 5 are v.o.a.

OpenStudy (anonymous):

ok..

OpenStudy (saifoo.khan):

Moving along. Question 4. Solve for x.

OpenStudy (saifoo.khan):

Rest all are easy too!

OpenStudy (anonymous):

solve for x right

OpenStudy (saifoo.khan):

Yup.

OpenStudy (anonymous):

what did you get? I want to check if i got it right

OpenStudy (saifoo.khan):

What do you get?

OpenStudy (anonymous):

30

OpenStudy (saifoo.khan):

\[\checkmark\]

OpenStudy (anonymous):

so its 30 degrees right

OpenStudy (saifoo.khan):

Right.

OpenStudy (anonymous):

yes were always done thanks for the help your a good teacher

OpenStudy (saifoo.khan):

Thank you! :)

OpenStudy (anonymous):

number 5?

OpenStudy (saifoo.khan):

So i have to do all of them? lol. How about you give them a try and i check your answers?

OpenStudy (anonymous):

how about 1 more 1 last one can you do number 9

OpenStudy (saifoo.khan):

Break the problem into parts..

OpenStudy (anonymous):

i want a 100percent on this assignment it will bring me to a B

OpenStudy (saifoo.khan):

They all are easy, you'll get it.

OpenStudy (saifoo.khan):

Suppose the angle be x. And since it's a supp. angle, hence (180 -x) And since it's 3 times of that, 3(180-x) And as it's 20 less out of it.. so: x=3(180-x) - 20 x=540-3x-20 4x=520 x=130*

OpenStudy (anonymous):

is this 9

OpenStudy (saifoo.khan):

Now let's check: If x is 130, then the supp angle of x is 180-130 = 50. Three times the supplement of x is 3*50 = 150. And 20 less than that is 150-20 = 130.

OpenStudy (saifoo.khan):

And yes, it's 9.

OpenStudy (anonymous):

thank you i really appreacitae it

OpenStudy (saifoo.khan):

You're welcome.

OpenStudy (anonymous):

is number 5 30 degrees ?

OpenStudy (saifoo.khan):

Nope.

OpenStudy (saifoo.khan):

The answer is not given. It's 120*.

OpenStudy (anonymous):

is number 6 B

OpenStudy (anonymous):

1and5

OpenStudy (saifoo.khan):

6 is b

OpenStudy (anonymous):

and number seven i gotten 6x - 40 = 3x + 5 6x - 3x = 5 + 40 3x = 45 x = 15 deg

OpenStudy (saifoo.khan):

correct

OpenStudy (anonymous):

number 8 y + 3x = 180 3x = 75 y + 75 = 180 y = 105 deg

OpenStudy (saifoo.khan):

3x = 75 x = 75/3 x = 25

OpenStudy (anonymous):

can u check my work if i copy the docment

OpenStudy (saifoo.khan):

Sure

OpenStudy (anonymous):

ok
