Find the acute angle between the sides of a rhombus whose diagonals are 8cm and 12cm long

Mathematics

Sergeu [11.5K]3 years ago

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.

The volume of a right circular cone is 45 cubic centimeters, and the radius of
Alisiya [41]

Answer:

5cm

Step-by-step explanation:

Given parameters:

Volume = 45cm³

Radius  = 3cm

Unknown:

Height of the cone  = ?

Solution:

Volume of cone is given as ;

  V = \frac{1}{3} \pi r² h

r is the radius

h is the height

      45  =  \frac{1}{3} \pix 3² x h

      45  = 3π x h

       h  = \frac{45}{3 x3.142}   = 4.77cm

5cm is the closest answer choice
