The number line shows the elevation of the bottom of a harbor and the elevation of a fish swimming close to the surface. A vertical number line labeled "Elevation (m)" goes from –12 to 2 by twos. Zero is labeled "sea level." There is a mark at negative 1.5 labeled "–1.5 meters" with an icon of a fish and another mark at negative 10.5 labeled "–10.5 meters bottom

What change in elevation is necessary for the fish to reach the bottom?

answer: it's upside down and i can't read it

step-by-step explanation:

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.

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.
