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
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 .
One of the most common example is Xenon tetraflouride. . 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.
In a molecule with a square pyramidal shape, there are two lone pairs and four outer atoms.
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.
