PROBLEM SOLVING A book on the care of tropical fish states that the pH level at the water should be
between 8.0 and 8.3 and the temperature at the water
should be between 76°F and 80°F. Let x be the pH
level and y be the temperature. Write and graph
a system of inequalities that describes the proper
pH level and temperature of the water. Compare
this graph with the graph you would obtan if the
temperatures were given in degrees Celsius.

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.
