Right and simplify an expression for the surface area of a square pyramid with a base edge length of SN & triangular faces with a height of seven in what is the surface area if the base edge length is 2.5 in

a. is correct

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.

its a, i had the same answer, its from study island right
