The sum of the digits of a two digit number is 7 when the digits are reversed, the number is 9 less than the original number. find the numbers

The two digit number is 43.

If flipped around, the number is 34, which is 9 less than 43. 4 + 3 = 7.

Hope this helps!

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

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.
