Question

PLEASE HELP ME!!!! :)

Answer 1

T=90 because:
first, solve for other variables 
(131)2+y*2=360 vertical angles are equal
y= 49, then solve for x,
x=180-73-42
x= 65
another side is 66 in x triangle.
then find the vertical angle between the z and the t triangle,

73+66+t triangle side= 180
t triangle side =41
49+41+t=180 
t=90
