Answer:
A=5/2a^2(5+2√5)
Step-by-step explanation:
In this scatter plot; we have people ages 10-80 years of age & the amount of texts sent per day. As one can tell by reviewing the graph; the highest amount of texts were sent at roughly the ages of 18-20. With this, the lowest amount of texts sent per day were between the ages of 70-80. We see a skyrocket between ages 10-20 in amount of texting however then we see a decent in average amount of texts as one ages.
Answer:
Surface area of Tetrahedron is 62.4 square units.
Note:(This is for only one surface of Tetrahedron)
Step-by-step explanation:
Given :
The shape is Tetrahedron.
length of Base = 12 unit.
length of Height = 10.4 unit
To Find :
Surface area of Tetrahedron = ?
Solution:
Tetrahedron:
It is a polyhedron composed of
4 Triangular faces, ( four triangular surface)
6 Straight edges, and
4 Vertex corners.
Base Shape: Triangle
Side Shape: Triangle
We need to find surface area of Tetrahedron
Therefore, one side surface area of Tetrahedron is 62.4 square units.
If we required total surface area of the Tetrahedron then it will be multiplied by four, because it has 4 surface or 4 face.
Total surface area of Tetrahedron = 4 × 62.4
= 249.6 square units
Answer:
C= 50°+ 31°( exterior angle)
C=81°
D+45°+96°=180°(the sum of angles in a triangle)
D=180-45°-96°
D=39°
h+52°=76°( exterior angle)
h=76°-52°
h=24°
f+32°=66°( exterior angle)
f=66°-32°
f=34°
r+45°+35°=180°(the sum of angles in a triangle)
r=180-45°-35°
r=100°
n+33°=80°( exterior angle)
n=80°-33°
n=47°
