I have encountered this problem before. The figure gave out 3 chords, 2 of which are diameters, and 1 radius.
A chord is a line segment that joins any two points on a circle.
A diameter is the longest chord on a circle. It originates at one side of the circle, passes through the middle point of the circle, and end on another side of the circle.
The chords in the figure area: AD, BE, and DE. AD and BE are diameters, they pass through F.
Among the choices: A.) AD and B.) BE are the chords.
CF and DF are radii. They only end up in the middle point of the circle.
Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles from 180 for A
A = 180° - (90 + 48)° = 180° - 138° = 42°
----------------------------------------------------------
tan48° = 
= 
Multiply both sides by a
a × tan48° = 18 ( divide both sides by tan48° )
a = 
≈ 16.2 ( to the nearest tenth )
-----------------------------------------------------------
sin48° = 
= 
Multiply both sides by c
c × sin48° = 18 ( divide both sides by sin48° )
c = 
≈ 24.2 ( to the nearest tenth )

Answer:
81,82,83
Step-by-step explanation:
What three consecutive integers have a sum of 246? Which means that the first number is 81, the second number is 81 + 1 and the third number is 81 + 2. Therefore, three consecutive integers that add up to 246 are 81, 82, and 83.
So George did't put parentheses around total snack amount to subtract his $15.He would need the total purchases to subtract amount by $15.
