Josh worked 50 hours frank worked 50 hours less and twice as many hours as josh did. How many hours did frank work

50 hours

Step-by-step explanation:

Josh = 50 hours

frank worked 50 hours less and twice as many hours as josh did.

Frank = 2(Josh) - 50 hours

= 2(50 hours) - 50 hours

= 100 hours - 50 hours

= 50 hours

Therefore, Frank worked for 50 hours

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.
