how do the values compare ? order the values from greatest to least 3/4 , - 1 3/4 , -1 1/4, - 2 1/4, 2 1/4, 1 1/4
natali 33 [55]

Answer:

The order of the values from greatest to least are as

\frac{21}{4} > \frac{11}{4} > \frac{3}{4} > \frac{-11}{4} > \frac{-13}{4} > \frac{-21}{4}

Step-by-step explanation:

Negative number goes on decreasing in this way as -1,-2,-3,-4,-5... and so on.

So,-11 > -13 > -21

Here the denominator is same and the numerator is in decreasing order i.e greatest to the least that is 21 > 11 > 3 > -11 > -13 >-21 .Therefore, the order is

\frac{21}{4} > \frac{11}{4} > \frac{3}{4} > \frac{-11}{4} > \frac{-13}{4} > \frac{-21}{4}

Find the acute angle between the sides of a rhombus whose diagonals are 8cm and 12cm long
Sergeu [11.5K]

Answer:

67.38°

Step-by-step explanation:

The diagonals of a rhombus intersect at their midpoints and make a right angle. They also divide the angles of the rhombus in two equal angles.

So, to find the acute angle of the rhombus, we can use the tangent relation of half this angle in the small triangle made when drawing the diagonals:

tan(angle/2) = 4 / 6

tan(angle/2) = 0.666

angle/2 = 33.69

angle = 67.38°

So the acute angle of the rhombus is 67.38 degrees.
