Answer:

m\angle ECB+m\angle EFB=180

m\angle CDB\cong m\angle EDF

m\angle CDB+m\angle DCB+m\angle CBD=180 \degree

Step-by-step explanation:

From the diagram, quadrilateral BCEF is a cyclic quadrilateral.

Opposite angles if a cyclic quadrilateral sum up to 180°

m\angle ECB+m\angle EFB=180

The diagonals intersect at D to form two pairs of vertical angles, and vertical angles are congruent.

m\angle CDB\cong m\angle EDF

Also sum of angles in triangle CBD is 180°.

m\angle CDB+m\angle DCB+m\angle CBD=180 \degree

The top graph is your answer.

Note that pink = cherry, and yellow = lemon. The question states that for every 4 cherry sold, one lemon is, therefore making the ratio 4 cherry: 1 lemon.

The next question is asking that how much in total is sold if there are 30 more cherry cones sold.

Let the amount of lemon cones sold be denoted by the variable, x.

The amount of cherry cones would still sold would be 4:1, but the amount is 30 more then x.

Multiply both sides of the ratio given by 10:

4 x 10 = 40

1 x 10 = 10

The result will give you 30 more cherry cones, and also give you the total of 50 cones in all.

50.
