In a right triangle, the length of the hypotenuse is 12m and the measure of one of the acute angles is 36°.Find the measure of the other acute angle and the lengths of the legs.

Answers

Answer:

Two legs are 7.0534230 and 9.708203932.

The acute angle is 54 degrees.

Step-by-step explanation:

For the legs, you can use these two formulas:

12*cos(36)

12*sin(36)

(Make sure you put the 36 in degrees)

For the acute angle, 90-54=36 degrees.

Answer:

The answer to your question is:

acute angle = 54°

legs 7 m y 9.7 m

Step-by-step explanation:

Data

Hypotenuse = 12 m

acute angle = 36°  = a

acute angle 2 = ?  = b

lengths of legs= ?

Process

The sum of the internal angles on a triangle equals 180°

                     a + b + 90 = 180

                    36 + b + 90 = 180

                    b = 180 - 126

                    b = 54°

sin Ф = opposite leg / hypotenuse

opposite leg = hypotenuse x sin Ф

opposite leg =  12 x sin 36

opposite leg = 7 m

Pythagorean theorem                

                                      c² = a² + b²

                                      a² = c² - b²

                                     a² = 12² - 7²

                                     a² = 144 - 49

                                     a ² = 95

                                     a = 9.7 m

How many outer atoms and lone pairs are present in a molecule with a square pyramidal shape?

Answers

Answer:

5 Outer and 1 lone pair

Step-by-step explanation:

A square pyramidal shape results when one of the bonds of an octahedron structure is occupied by a lone pair.

Hence there are 5 bonded atoms and one lone pair. The hybridization about the central atom is sp^(3) d^2.

One of the most common example is Xenon tetraflouride. XeF_4. Looking at its structure we can see that it has 5 pairs of outer atoms and one lone pair. With its coordination number 5. The shape of the orbitals is octahedral.

Final answer:

In a molecule with a square pyramidal shape, there are two lone pairs and four outer atoms.

Explanation:

When a central atom has two lone electron pairs and four bonding regions, we have an octahedral electron-pair geometry. The two lone pairs are on opposite sides of the octahedron (180° apart), giving a square planar molecular structure that minimizes lone pair-lone pair repulsions.
