A. 4 - (-14 - 2) = 4 + 14 + 2 ------------------------WRONG

B. (4 - 14 ) - 2 = 4 - 14 - 2 --------------------------WRONG

C. 4 - (-14) - (2) = 4 + 14 - 2 ------------------------RIGHT

D. 4 + 14 + (-2) = 4 + 14 - 2 ------------------------RIGHT

E. - (-4 - 14) - 2 = 4 + 14 - 2 ------------------------RIGHT

Answer: C, D and E.

4 + (14 - 12) = 4 + (12) = 16

A. 4 - (-14 - 2) = 4 - (-16) = 20. Not equivalent.

B. (4 - 14) - 2 = (-10) - 2 = -12. Not equivalent.

C. 4 - (-14) - (2) = 18 - 2 = 16. Equivalent.

D. 4 + 14 + (-2) = 18 + (-2) = 16. Equivalent.

E. - (-4 - 14) - 2 = - (-18) - 2 = 18 - 2 = 16. Equivalent.

Choices C, D, and E are all equivalent to the expression 4 + (14 - 2).

two sides of a parallelogram meet at an angle of 50 degrees. If the length of one side is 3 meters and the length of the other s

Anon25 [30]

Answer:

The longer diagonal has a length of 7.3 meters.

The angles are 31.65° and 18.35°

Step-by-step explanation:

If one angle of the parallelogram is 50°, another angle is also 50° and the other two angles are the supplement of this angle. so the other three angles are:

50°, 130° and 130°.

The longer diagonal will be the one opposite to the bigger angle (130°), and this diagonal divides the parallelogram in two triangles.

Using the law of cosines in one of these two triangles, we have:

$diagonal^2 = a^2 + b^2 - 2ab*cos(130\°)$

$diagonal^2 = 3^2 + 5^2 - 2*3*5*(-0.6428)$

$diagonal^2 = 53.284$

$diagonal = 7.3\ meters$

So the longer diagonal has a length of 7.3 meters.

To find the angles that this diagonal forms with the sides, we can use the law of sines:

$a / sin(A) = b/sin(B)$

$5 / sin(A) = diagonal / sin(130)$

$sin(A) = 5 * sin(130) / 7.3$

$sin(A) = 0.5247$

$A = 31.65\°$

The other angle is B = 50 - 31.65 = 18.35°
