Can anyone figure out the angle "t"...? I've been stuck on it for way too long, I have no clue what steps to do. Thank you very much

"y"  is supplemental to the  131° angle  =  49°

 

And since the angle at the bottom left of the small triangle containing "t"  is a vertical angle to "y", its measure  is also 49°

 

And the angle supplemental to the 142°  angle = 38°

 

So  "w"  in the small triangle on the bottom right =  180  - 49 - 38  = 93°

 

And the vertical angle to "w" in the small triangle at the top right  also  = 93°

 

So...the remaining angle in this triangle  =  180 - 93 - 42  = 45°

 

But this angle is a vertical angle to the angle at the bottom right in the small triangle at the top

 

So   ...  "t"     =    180  - 49  - 45  =  86°

 

 

cool cool cool
