Given isosceles right triangle CDE with m∠D = 90, sin C = sin D

Butoxors [25]

Answer:True

Step-by-step explanation:

Given

$\angle D=90^{\circ}$

For isosceles triangle , CD=DE (x=y)

from figure,

$\sin C=\dfrac{y}{H}\\\\\sin D=\dfrac{x}{H}\\\\\text{CD=DE}\\\\\therefore \sin C=\sin D=\dfrac{x}{H}=\dfrac{y}{H}$

Thus, the given statement is true

the volume of a box is 45x^3 + 198x^2 + 189x. find expressions for the possible dimensions of the prism

Oxana [17]

Answer:

length, width, and height are (b+2), (b-2), (b+3)

Step-by-step explanation:

Doing what the problem statement tells you to do, you get ...

(b^3 +3b^2) -(4b +12)

= b^2(b +3) -4(b +3) . . . factor each pair of terms

= (b^2 -4)(b +3) . . . write as a product

= (b -2)(b +2)(b +3) . . . use the factoring of the difference of squares

The three factors are (b-2) , (b+2) , and (b+3). We have no clue as to how to associate those with length, width, and height. We just know these are the dimensions of the box.
