Answer:
t=44°
Step-by-step explanation:
The sum of the interior angles of any pentagon is always 540 degrees.
Let's set up an equation with this information: (all figures are in degrees)
[tex]t+3t+t+32+149+139=540[/tex]
Now we combine all like terms.
[tex]5t+320=540[/tex]
Now begin to isolate t be subtracting 320 from both sides.
[tex]5t=220[/tex]
Finally divide both sides by 5 to isolate t.
t=44°
