Answer:

7) 65°
8) 25°

Step-by-step explanation:

<u>Question 7</u>

Angle formed by 2 chords is half of the sum of the intercepted arcs

x = 1/2(72° + 58°) = 1/2(130°) = 65°

<u>Question 8</u>

Angle formed by 2 secants is half of the difference of the intercepted arcs

x = 1/2(360° - (130° + 98° + 41°) - 41°) = 1/2(50°) = 25°
