# Math Help - Unknown Angles

1. ## Unknown Angles

2. why didnt the images appear ?

3. wanted to confirm the answer.

i get for the 1st one x=36 but what will be y ?

for second x=25

and for third
x+58+(180-79)=180
x=21

so y+3(21)+79=180
y=38

Are the answers right ?

4. Hi haftakhan,
Why didn't you write the equation for problem 1?
When you write the equations to find unknowns and then check to see that your triangles all total 180 you don't need confirmation. Relative to 1 y cannot be defined from your drawing.

5. in question 1,wont y be equal to 2x ?

6. Hi haftakan,
Tell me why you believe that y=2x.In other words prove it or say it is not so
