12222220 times 50 +60-80times 30000005

1.1e+16

Step-by-step explanation:

I did:

12222220 times 50 +60-80times 30000005

12222220*(50+60-80)*30000005

(50+60-80): (50+60)-80; 110-80=30

12222220*30=366666600

366666600*30000005

=1.1e+16

I hope this is correct

-1788889340

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.
