Answer:
Rectangular Pyramid
Step-by-step explanation:
Rectangular Pyramid-It has 5 faces, 8 edges and 5 vertices.
Answer:
Step-by-step explanation:
To solve this you need the Law of sines
- sin A / a = sin B / b = sin C / c
a, b, c are the sides opposite to angles A, B and C respectively
Applied to the given triangle we have one side given, the opposite angle to be found.
- sin 28 / x = sin (180 - 28 - 126) / 8.2
- sin 28 / x = sin 26 / 8.2
- x = 8.2 sin 28 / sin 26
- x = 8.8 (rounded)
Answer is D.
Tempted to give you my number for help.
2.83 if rounded. 2.82842712475 would be the actual.
Hope this helped!
X=-2/5
Steps:
6^x/3 +2 = 6^-14x/3
x/3+2 = -14x/3.
x +6 = -14x (multiply both sides by 3)
x = -14x - 6 (Substract 6 from both sides)
x + 14x = -6 (add 14x to both sides)
15x = -6 (collect like terms)
x = -2/5 (divide both sides by 15)
