Can someone help me here​
bearhunter [10]

Answer:

1.

Step-by-step explanation:

1. sin 241 = sin(61 + π) = -sin61 = -t^(1/2)

2. sin^2 + cos^2 =1, cos 61= (1-t)^(1/2)

3. [2sin^2 (x)sin(x) +2cos^2 (x)sin(x)]/2cos(x) = 2sin(x) / 2cos(x) = tan(x)

4. tan (x), x do not equal to (π/2 +or- kπ)

x do not equal to 90,270。

Which statement proves that parallelogram KLMN is a rhombus?
IrinaVladis [17]

Answer:

It is the last option.

Step-by-step explanation:

The diagonals of a rhombus (KM and NL ) are perpendicular. That is shown by the diagonals having slopes of 1 and -1.

Recall that when  2 lines are perpendicular then m1 * m2 = -1 , where m1 and m2 are the slopes of the lines.
