14. this week, anita spent 3 1/2 h practicing the piano. she also spent 6 1/4 h at soccer practice and 4 1/3 h on the telephone. a) how much time, in total, did anita spend on the piano and at soccer? b) how much more time did anita spend at soccer than on the phone?
this is fractions

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.

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
