The ratio 2.5 metres to 60 centimetres can be written in the form 1: n find the valur of n

The value of n is

Step-by-step explanation:

we know that

1 m=100 cm

step 1

Convert 2.5 m to cm

2.5 m=2.5*100=250 cm

step 2

Find the ratio

Divide by 25 both numerator and denominator

therefore

The value of n is

a) 15/7

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.
