Agroundskeeper is tasked with fertilizing the grass of a triangular courtyard. to determine how much fertilizer he should buy, he must know the area of the courtyard. the owner informs the groundskeeper that the base of the courtyard is ì90 meters and the height of the courtyard is 10+ì3meters. what is the area of the courtyard? (recall that the area of a triangle is , where b is the base and h is the he

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
