Answer:
NC = 7.7
C = 63.6°
T = 26.4°
Step-by-step explanation:
✔️Apply pythagorean theorem to find the length of NC:
NC = √(17.2² - 15.4²) = √58.68
NC ≈ 7.7
✔️Apply trigonometric function to find Angle T:
Reference angle = T
Hypotenuse = 17.2
Adjacent length = 15.4
Apply CAH, thus:



T ≈ 26.4°
✔️C = 180 - (90 + 26.4) (sum of triangle)
C = 63.6°
