In triangle mpn, angle p is a right angle. if cos n= 3/5 which of the following statements is true sinm= 5/3 sing m= 5/4 sinm= 4/5 sinn= 3/5

sinM=3/5

Step-by-step explanation:

Sin N =

Step-by-step explanation:

Since we have given that

In triangle MPN, ∠P=90°

As we know the formula for "Trigonometric Ratios":

By Pythagorus theorem , we get

So, we get,

Hence, Sin N =

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
