Explain why the value of the sine ratio for an acute agle of a right triangle must be less than 1

Explanation:

The sine is the ratio of the opposite side to the hypotenuse. When the ange is acute (< 90°), the hypotenuse is longer than the opposite side of the right triangle, so the ratio of that side length to the hypotenuse must be less than 1.

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.
