Answer: ∠AOB = 100°

Step-by-step explanation:

This is found in the circle geometry. The theorem in solving this stated that the angle which an arc of a circle subtends at the centre of the circle is twice that which it subtends at any point on the remaining part of the circumference of the circle

Therefore

∠AOB = 2 x ∠ACB

= 2 x 50°

= 100°

Solve the equation log4(x + 20) = 3

andre [41]

Answer:

x = 44

Step-by-step explanation:

log4(x + 20) = 3

Raise each side to the power of 4

4^ log4(x + 20) = 4^3

x+20 = 4^3

x+20 = 64

Subtract 20 from each side

x+20-20 = 64-20

x = 44
