The average height of Susan's 8th grade class is 56 inches. However, the height of any student in the class can vary by up to 4 inches from the average. Which inequality shows all the possible heights (h) for any given student in the class?

a: 1/6, j: 1/4

step-by-step explanation: you are welcome

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.

answer: a.12cm

step-by-step explanation:

the answer is

a.

x = 42

y = 10
