In △ekl, m∠k = 90º, m∠e = 25º, ek = 3 cm,

kh - altitude. find eh.

pi x^2

step-by-step explanation:

pi times x squared

t= 1/3.

hope this .

step-by-step explanation:

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0

1/4 is the answer if i recall correctly.
