Based on the given angle measures, which triangle has side length measures that could be correct?

Answer

The triangle in the figure 4 is correct .

Reason

by using the trignometric identity

Thus

Now in the figure (1)

on simplify

thus side length measures in the figure (1) is not correct .

Now in the figure (2)

thus side length measures in the figure (2) is not correct .

Now in the figure (3)

thus side length measures in the figure (3) is not correct .

Now in the figure (4)

 Therefore the figure (4) is correct triangle has side length measures that could be correct

Hence proved

answer: procent 54 wynosi 33,33%

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
