Lisa is 10 centimeters taller than her friend ian. ian is 14 centimeters taller than jim. every month, their heights increase by 2 centimeters. in 7 months, the sum of ian's and jim's heights will be 170 centimeters more than lisa's height. how tall is ian now?

1 1/5

step-by-step explanation:

the answer is d on edge

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.
