The height of a stuntperson jumping off a building that is 20 m high is modeled by the equation h = 20 - 5t, where t is
the time in seconds. A high-speed camera is ready to film the person between 15 m and 10 m above the ground. For
which interval of time should the camera film the person?

Step-by-step explanation:

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.
