The measure of an angle is 51°. What is the measure of its supplement? A. 39° B. 49° C. 129° D. 139°
Supplement of angle 'x' is just 180-x
two supplementary angles always add to 180 degrees x+y = 180 51+y = 180 y = ??
C

Thanks :) 2 more?
sure
The lines intersect at point K. http://static.k12.com/calms_media/media/1421000_1421500/1421001/1/461d4a8736bac521aee4fecbb679517fbeac36b2/MS_Alg_130924_281813.jpg What is the value of x? A. 23 B. 30 C. 46 D. 62
vertically Opposite angles are congruent.
5x-53 = 3x-7 can you find 'x' from here ?
um... B?
... um.... ok?
lol, did you even calculate? or it was just your guess ? because B is correct :P
that was a guess XD but I understand that I needed to multiply and make it match :D
oh wait, B is not correct
I didn't get B
5x-53 = 3x-7 2x = 53-7 = 46 x=23
oh... oops sorry
That's what I got too :P
yeah, sometimes when you solve a problem mentally, such silly mistakes happen :P

I solved and got A mentally, but mistakes happen.. specially when they really matter xD
but thanks for noticing that XD but how would I do this one?
Ok first you must find x, and by looking at the picture you can find 8x+9x+5=90
angle BHR and angle NHD are vertically opposite angles
wait I got this 1 sec :D
nvm continue explaining
i'll let venny take this one :)
And what @hartnn said, angle BHR and NHD are verically opposite so the angle we need to find is equal to 8x
Have you solved for x yet? or do you need help with that
I need help sorry
Its okay! 8x+9x+5=90 The first step is to combine like terms, 17x+5=90 next you need to subtract 5 so 17x=85 Divide both sides by 17
what do you get for x?
1x=5?
Yes! and since angle NHD=angleBHR, we know that the angle we are trying to find is equal to 8x, So to find that we multiply 5(8)
40 so its A?
Yep! I got A too
XD I FEEL GREAT! Thank you soo much :)
No problem
thanks to @hartnn too :)
indeed for showing me how to solve the 1st one, thanks everyone! :) :D XD
welcome ^_^ happy to help :)
th edog of os is @hartnn
can I hit you guys up later if I need the help?
