The watch repairman needs to replace the battery on some watches he has 43 minutes before closing how many batteries can he replace if each replacement takes 8 minutes and how many minutes will be left over

5 batteries with a leftover time of 3 minutes

Step-by-step explanation:

If it takes the watch repairman 8 minutes to replace a battery on the watches

In 43 minutes, he will be able to replace batteries on the watches

=

Therefore the watch repairman can replace 5 watch batteries.

He will have 3 minutes left over.

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.
