Jamie is hiking up a small mountain at a constant rate of 300 feet/hour. He must climb 1,500 feet to reach the peak. After that, he hikes down at the same rate to the base of the mountain. The equation that can be used to find the number of hours, t, after which Jamie's distance from the peak will be 900 feet is . Jamie will be 900 feet from the peak after hours and after hours.

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.
