B. Double 5 plus 1 equals 11 and add 1 to 5 doubled equals 12.
Step-by-step explanation:
By arc sum Postulate of a circle:
2 x + 3x + 4x = 360°
9x = 360°
x = 360°/9
x = 40°
3x = 3* 40° = 120°
By inscribed angle theorem:
By tangent secant theorem:
Since, measure of central angle is equal to the measure of its corresponding minor arc.
By angle sum Postulate of a triangle:
The flowers cost $12
40.00-10.75=$29.25
$29.25-3.25=$26.00
$26.00-$12.00=14
