Ahang glider is soaring over a 100-acre area that consists of thick forest and open fields. in the diagram below, the forested area is shaded in green and the open field is the white space. upon landing, the hang glider realizes she has dropped her keys. what is the probability that her keys have landed within the forest? the blacked out middle section of the pyramid is 20 acres a 0.2 b 0.6 c 0.8 d 1.0

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.
