Since angle TTC is an isosceles triangle with a vertex angle at /, this means that angle T and angle C are congruent. Additionally, angle f is a 90-degree angle.
The sum of the angles in a triangle is 180 degrees. Therefore, we can set up the following equation:
angle T + angle T + 90 = 180
Simplifying this equation, we get:
2 * angle T + 90 = 180
Subtracting 90 from both sides, we have:
2 * angle T = 90
Dividing both sides by 2, we find:
angle T = 45 degrees.
Therefore, the measure of angle T is 45 degrees.
The answer is B. 45
