Last month John spent 75.00 dollars on games. This month he only spent $63.00. He spent ___ percent less this month.

84%

Step-by-step explanation:

you cross multiply 63 and 100, then you divide by 75

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
