Answer: c
Step-by-step explanation:
bc
Step-by-step explanation:
10×10+24×24= third side ×third side
third side ×third side =100+576
third side × third side=676
third side=√676
third side=26
Y=Ф + 8/(ФcosФ) ==> note that
dy/dФ = 1 - 8/[(ФcosФ)]² x (-8sinФ) ==> dy/dФ = 1+[(64sinФ)/Фcos²Ф]
==> dy/dФ = 1+ 64tanФ/Ф or dy/dФ = (Ф+tanФ)/Ф
Let

. You have

.
Taking the derivative, you get

The linear approximation to

near

is given by

So the value of

can be estimated as
