F) If two angles are equal, they must be corresponding.

navik [9.2K]

Answer:

False

Step-by-step explanation:

This is an erroneous statement, so we presume it is supposed to be a true/false question. It is false.

Corresponding angles are only congruent in certain geometries. One such is where a transversal crosses parallel lines. There are a number of sets of corresponding angles in that geometry, and additional congruent angles that are not "corresponding."

Base angles in an isosceles triangle are equal, but not "corresponding." The presumption that equal angles are corresponding is FALSE.

The pilot of a Coast Guard patrol aircraft on a search mission had just spotted a disabled fishing trawler and decided to go in

Svetllana [295]

Answer:

$\frac{dD}{dt}= 181\frac{168}{1600}$

Step-by-step explanation:

h= 1000 ft

dx/dt= 232 ft/sec

D= 1600 ft

First, we have to find a distance x ( shown in the figure)

applying pythagorus theorem

D^2= h^2+x^2................1

x^2= D^2-h^2

= 1600^2-1000^2

x^2= 1560000

x=1248.99 m

Now we can find out how fast the aircraft is receding from the trawler

( notice that the height is not changing)

so differentiating equation 1 w.r.t t we get

$\frac{d}{dt} (D^2)= \frac{d}{dt}(h^2+x^2)$

2DD'= 2hh'+2xx'

$D\frac{dD}{dt}= h\frac{dh}{dt}+x\frac{dx}{dt}$

now putting values we get

$1600\frac{dD}{dt}= 1000\times0+232\times1249$

$\frac{dD}{dt}= 181\frac{168}{1600}$
