I need the answers to these 5 problems like asap:(
look at there wher it says `choose one` that would help you to get answer in 30 sec
I tried its not working can u try for me:(((
anyways for first one according to the consecutive interior angles |dw:1442370605037:dw|
thank you so much
so what's the answer for first one ?
70 degrees right?
70+110 =180 both sides are equal ? if yes then 70 is correct :=)
Can you help with the other 4 please?
I could help you in the other subjects
What subjects do you need?
alright for 2nd one you should know vertical angles are equal |dw:1442370863707:dw| and according to the definition:angles that are in the same position in terms of the transversal are known as corresponding angles
remember that's an example you should look up at ur question to find correct answer
I dont get it im confused
vertical (opposite side of each angles ) are congruent|dw:1442371175271:dw| in this example a and b are vertical angles so a=b are congruent
now look at the 2nd question which angle is congruent to< B ?
d,c, and a but there not options:((
oh c g and f!
|dw:1442371341005:dw| which angle is congruent to angle B B and D are vertical angles ?
yes that's right
Thank you so much! only 3 left:)
|dw:1442371753023:dw|which one is the vertical angle of 2x-70 ?
A? Could you explain I havent taken geo ever until now
yes right i posted above `vertical` angles `Vertical Angles are the angles opposite each other when two lines cross`
so you can replace `a` with 2x-70 |dw:1442371935512:dw|
now alternate interior angles `The pairs of angles on opposite sides of the transversal but inside the two lines are called Alternate Interior Angles.` i'll give u an example |dw:1442372027808:dw| interior means inside two parallel lines
so which angle is alternate interior of 2x-70 ?
|dw:1442372128331:dw| id a = 2x-70 (vertical angles ) now find alternate interior angle of 2x-70
like 5y and g are alternate interior angles so 5y=g
x+30 is the alternate angle
alternate angle is C c and x+30 are vertical ane since vertical angles are equal so you can write it as 2x-30=x+30 now solve for x
hmm no try again 2x-70=x+30
ps try again it's 2x-70 my bad
yes right now replace x with 100 into 2x-70
let me know what you get
yes right and we know angle a equal to 2x-70 so we can replace a with it |dw:1442372724550:dw| stright line equal to 180 degree so 130 +5y =10 solve for y
ohh god lag >.< 130+5y =180
ok! THank you soo much! 2 moree
