Solve for x in the given interval.

sec x= -2√3/3, for π/2 ≤x≤π

b.

Step-by-step explanation:

The given function is

Recall that the reciprocal of the cosine ratio is the secant ratio.

This implies that;

We take the inverse cosine of both sides to obtain;

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

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.
