Answer:

x=9

Step-by-step explanation:

Arc AC=106°

Angle ABC=106/2

Answer:

for the second

Step-by-step explanation:

m(<ABC) = 1/2 m( AC)

m(AB) + m(BC) + m(AC) = 360°

92° + 162° + (AC) = 360°

m(AC) = 106°

m(<ABC) = 1/2m(AC)

= 1/2(106°)

= 53°

(7x-10)° = 53°

7x = 53°+10°

7x = 63°

x = 9
