Answer: 60 degrees
The figure there is a parallelogram
< H = 2x + 60
< T = x + 30
Therefore, supplementary angles is 180 degrees
< H + < T = 180
2x + 60 + x + 30 = 180
Collect the like terms
2x + x + 60 + 30 = 180
3x + 90 = 180
3x = 180 - 90
3x = 90
Divide both sides by 3
3x/3 = 90/3
x = 30
Since < T = x + 30
Hence,
< T = 30 + 30
< T = 60 degrees
