Hi guys, i'm new here and i'm not english native, so my math english could be bad, anyway, my question refers to this pic. why if i choose to put t=5x i have to put 1/sqrt(5) outside the integral? i can't understand this for your answer

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

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.
