Mature soil is composed of three layers the uppermost being topsoil jamal is planting a bush that needs an hole 18 cm deep for the roots. the instructions suggest an additional 8cm depth for cushion. if jamal wants to add mor cushion and the topsoil i. is yard 30 cm deep how much more cushions can he add and still remain on the topsoil layer?

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.
