Fifty people who watch television were recently polled as to which type of program they preferred. The results are shown in
the table.

What percent of those surveyed preferred to watch new programs?

A) 10%

Step-by-step explanation:

take the number who like to watch news and divide by 50 (total number)

5/50 = 0.1

multiply by 100 to get percent

.1 x 100 = 10

10%

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.
