The scale one a map is 1 : 15000 how many kilometres on the ground would be represented by 12 cm on the map?

n

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

step-by-step explanation:

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.
