How do you round a digit to the nearest place

Let's say we have the decimal 6.987654321

If we wanted to round it to the tenth decimal place, we'd write it as 6.98 because the tenth is to the second decimal place.

If we wanted to round it to the thousandth decimal place, we'd write it as 6.987.

Ten-thousandth would be 6.9876

hundred-thousandth would b 6.98765

And so on

b

step-by-step explanation:

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.
