An airplane departs an airport and climbs to an altitude of 2,600 feet. the plane climbs 300 feet more to an altitude 2,900 feet. which number is the additive inverse of the plane's height? a) −2,900 b) −300 c) 2,600 d) 300

The answer is A) -2,900

1) An airplane departs an airport and climbs to an altitude of 2,600 feet. The plane climbs 300 feet more to an

altitude 2,900 feet. Which number is the additive inverse of the plane's height?

A) −2,900

Explanation:

−2,900

plane's altitude = 2900 feet

Therefore, the additive inverse of the plane's altitude is −2,900. The sum of a number and its additive inverse

is 0.

2,900 + (−2,900) = 0

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
