The number of pages that kline can read varies directly with the time he spends reading if he reads 13 pages in 25 minutes how many can he read in two hours

  62.4 pages

Step-by-step explanation:

Let n represent the number of pages he can read in 2 hours (120 minutes). Then the proportion can be written ...

  n/120 = 13/25

  n = 120(13/25) = 312/5 = 62.4

Kline can read about 62.4 pages in 2 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.
