Question

Help i dont get how to solve this problem: http://gyazo.com/b72c11d97f13878bb1f10bd280e55cbe

Answer 1

i think 130degrees

Answer 2

I think you're correct.

Answer 3

you have vertically opposite angles. angle F forms vertically opposite angle of 30 +40
and angle G forms vertically opposite angle of 60.
therefore 60 + 70 = 130 degrees

Answer 4

Can you explain how to do it because my pre-test is full of these. like this one http://gyazo.com/d1f4319aa02568bed6a0bac9a4bcfd22

Answer 5

same as 155

Answer 6

lines are parallel so the angles are the same in both

Answer 7

So how do you solve it?

Answer 8

those are corresponding angles, and corresponding angles have equal measures :)

Answer 9

ya but how do i solve it? to get 155

Answer 10

you don't solve it :p you just know that :p

Answer 11

you dont need to solve
you just write that this angle is equal to 155 degree as this angle is corresponding to the angle having 155 degree, therefore the angle equals 15

Answer 12

i mean 155 degree :p

Answer 13

ahhh i get it now

Answer 14

yea ;)
