1. ∠T ≅ ∠T . . . . reflexive property of congruence
2. ∠TAN ≅ ∠TRI . . . . corresponding angles postulate
3. ΔTAN ~ ΔTRI . . . . AA similarity theorem
<h3>3b)</h3>
Corresponding parts of similar triangles are proportional, so ...
... NI/AR = TN/AT
... NI/(2 cm) = (12 cm)/(8 cm)
... NI = (2 cm)·(12/8)
... NI = 3 cm
1/2 × 40 = 2x + 8
⇔ 20 = 2x + 8
⇔ 12 = 2x
⇔ x = 6

I know I'm really late but I hope I helped
Answer:
x = 1/8(k-c)
Step-by-step explanation:
8x + c = k
Subtract c from each side
8x +c-c = k-c
8x = k-c
Divide each side by 8
8x/8 = (k-c)/8
x = 1/8(k-c)
