Answer:
10 5
Step-by-step explanation:
Let the two sides of a right triangle be equal to one, which means that the hypotenuse is √2
Since cosa=adjacent side / hypotenuse
cos45=1/√2
We can rationalize the denominator by multiplying numerator and denominator by √2
√(2)/2
or if you prefer: √(1/2)
It's 2 7/12

Answer: 
Step-by-step explanation:
Point slope form:
, where n=slope , (a,b) is the point through which line passes.
If slope of the line = m and line passes through
and
:-

So, the equivalent equations are :

Answer:
using pythagoras theorem
H^2=P^2+B^2
here h=MN ,opposite(P) be 15 and adjacent(B) be 16
(MN)2=15^2+16^2
(MN)^2=225+256
MN=
MN=21.93
after rounding off MN=21.9
