Answer:
120°
Explanation:
To find the measure of angle t in the pentagon, we can use the property that the sum of the interior angles of a pentagon is equal to 540 degrees.
So, we can set up an equation:
80° + 90° + 130° + 120° + t = 540°
Simplifying the equation:
420° + t = 540°
Next, we can isolate the variable t by subtracting 420° from both sides of the equation:
t = 540° - 420°
t = 120°
Therefore, the measure of angle t in the pentagon is 120 degrees.
Hope this helps!
