115

study312 · Answer

c = 115

rebeccaxhawaii · Answer

good

study312 · Answer

now what?

jhonyy9 · Answer

so than you see the opposite angle to angle a is 40 degree so this mean that angle a how many will be too ?

study312 · Answer

um... huh?

study312 · Answer

two a and b?

jhonyy9 · Answer

and with this inside this triangle you know the angle a ,you know that there is a right angle what has how many degree and you know that the sum of angles inside a triangle is equal how many - so from these all you can calculi easy the measure of angle b - yes ?

jhonyy9 · Answer

study looke please |dw:1455920093353:dw|

study312 · Answer

it kinda cut, was the last word angle?

jhonyy9 · Answer

so how many degree has angle a ?

study312 · Answer

I don't understand what you mean?

jhonyy9 · Answer

i have posted an image - yes 

angle opposite to angle a has 40 degree exactly how in your posted image - please check it 

so angle a has the same measure with opposite angle x - so how many degree will be angle a ?

study312 · Answer

90 - 40?

jhonyy9 · Answer

what is this 90 ?

jhonyy9 · Answer

first just the measure of angle a please

jhonyy9 · Answer

after what you get the angle a you can calculi the measure of angle b 

ok.?

study312 · Answer

well if I remember correctly a vertical angle is 90 degrees

study312 · Answer

so 90 - 40 = a???

jhonyy9 · Answer

what you wan with this - i dont understand you - sorry 

than you wan getting the angle a please answer what i ask - believe me - will get it sure easy

study312 · Answer

I don't get what you want me to do?

jhonyy9 · Answer

but this is very very easy 

you need just answer my question please 

1. what is the measure of angle opposite to angle a on my posted image ?

study312 · Answer

b

study312 · Answer

I said b before

jhonyy9 · Answer

not b opposite to angle a is angle x

study312 · Answer

x is not on the picture

jhonyy9 · Answer

indifferent check please what i have posted please just for more understandably to you

jhonyy9 · Answer

opposite to angle a is angle x hwta has 40 degree so this mean that angle a has how many degree too ?

jhonyy9 · Answer

what has - sorry

study312 · Answer

40

jhonyy9 · Answer

yes so you know that angle a has 40 degree and you know again that inside this triangle there is a right angle what has how many degree ?

study312 · Answer

idk can you tell me?

jhonyy9 · Answer

a right angle how many degree has ?|dw:1455921299662:dw|

study312 · Answer

90

jhonyy9 · Answer

yes

jhonyy9 · Answer

so you know again that the sum of angles of a triangle is equal how many ?

study312 · Answer

40 + 90?

jhonyy9 · Answer

no

the sum of angles inside a triangle  equal how many degree ?

jhonyy9 · Answer

there are 3 angles because this is triangle

study312 · Answer

idk 90?

jhonyy9 · Answer

90 is just a half of this sum  - so than how many wiil be the total sum ?

study312 · Answer

90 - 40

jhonyy9 · Answer

sum
----- = 90 
  2 

sum = ?

study312 · Answer

180

jhonyy9 · Answer

yes - learn it because will use so much time

jhonyy9 · Answer

so you know that angle a=40 and there is again an angle with 90 degree and you know the sum of these 3 angles of this triangle so how you calculi the measure of 3rd angle ?

study312 · Answer

90 - 40

study312 · Answer

or wait 180 - 40?
