Question

Can you help me how to find the measure of angles of a triangle?

Answer 1

let me give a sample..

Answer 2

in first triangle,
180 - 38 = 142.. and then?

Answer 3

2x - 3 + 38 + x = 180 ( in triangle left one)
x = 145/3 (put this in x containing equations )
x = y ( vertically opposite angles are equal )

now
y + w + 4w - 5 =180 (you know value of 'y' which is equal to 'x'. put this here and find w )

you know x, y ,and w.
put their values in the respective angles and get their value

:) --- hope it works!!!

Answer 4

@maddyx OMG. You are so helpful! Thank you so much<3

Answer 5

2x - 23 + 38 + x = 180 ( in triangle left one)
x = 55 (put this in x containing equations )
x = y ( vertically opposite angles are equal )

now
y + w + 4w - 5 =180 (you know value of 'y' which is equal to 'x'. put this here and find w )

you know x, y ,and w.
put their values in the respective angles and get their value

:) --- hope it works!!!


(THIS IS EDITED ONE...I PUT SOME VALUES WRONG)
