Answer:
They paid 16 3/4% tax
Step-by-step explanation:
9%+1 3/4%+6%=16 3/4%
Answer:
Step-by-step explanation:
This is a Pythagorean Theorem Question
c^2 = a^2 + b^2
c= sqrt(5)
a = x
b = x This is an isosceles right triangle. The vertical side and the horizontal side are equal.
x^2 + x^2 = sqrt(5)^2
2x^2 = 5 Divide both sides by 2
x^2 = 5/2 Take the sqrt of both sides.
√x^2 = √5 / √2 Multiply right side by √2 on both top and bottom
x = √5*√2 / √2*√2
x = √10 /2
Answer: 32 sides
Step-by-step explanation:
Formula for interior angle of a polygon = ( n - 2 )180°, where n is the number of sides of the polygon
Now equate the formula to 5400°
( n - 2 ) × 180° = 5400°
open bracket by multiply by 180°
180n° - 360° = 5400°
180n° = 5400° + 360°
180n° = 5760
n = ⁵⁷⁶⁰/₁₈₀
n = 32
so the polygon has 32 sides
It is obviously 65,duh, what is the value of 65
Answer:
Area of square pyramid is
.
Step-by-step explanation:
Diagram of the given scenario is shown below,
Given that,
The Great Pyramid in Giza, Egypt is a square pyramid. The area of base shape is made up with square is
. The side of the square is
and The height of each triangle is
.
So, Area of Square shape = 
Side of square = 
Height of each triangle = 
Finding the Height of triangular shape which is here known as slant height.
In Δ ABO, applying Right angle pythagorean Theorem,
Base
= 
Height
= 
Now,
∴ 
⇒ 
⇒ 
⇒ 
⇒ 
Then,
Area of square pyramid = 
=
= 
= 
= 
Hence, Area of square pyramid is
.
