Answer:

C. 78°

Step-by-step explanation:

The sum of angles in a triangle is 180°.

(7x-6)° +(4x+11)° +43° = 180°

11x +48 = 180 . . . . . divide by °, simplify

11x = 132 . . . . . . . subtract 48

x = 12 . . . . . . . divide by 11

Then the measure of angle T is ...

∠T = (7x -6)° = (7(12) -6)°

∠T = 78°

$q=\frac{h^{2}-k^{2}}{3m}$
Cross-multiplying and rearranging, we get:
$k^{2}=h^{2}-3mq$
or written without using latex:
k^2 = h^2 - 3mq
