Find the measure of b in the picture

The correct answer option is B. 126°.

Step-by-step explanation:

We are given a figure where triangle within a triangle is inscribed in a circle and we are to find the measure of angle b.

From the given figure, we can see that the angle b is at the center of the circle. So this must be an isosceles with two sides equal to each other.

If that is the case, then angle a must be equal to 27° so we can find the measure of angle b.

∠b = 180° - (27° + 27°)

∠b = 126°

all three statements are true

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
