Answer:
yes it is an equilateral triangle
To find the volume,we would first need to find the height of square pyramid, by it's base edge and slant height using Pythagoras theorem:
We can then use the pyramid formula to find the volume:
In this case,the volume will be:
10×_/69×1/3
=27.68874...
≈27.7 units^3
Hope it helps!
Answer:
22cm,24cm,24cm
Step-by-step explanation:
Let us call one of the other sides x
the shortest side = 2x-26
in an isosceles, 2 sides are equal (x in this case)
so we now have sides of x,x and 2x-26
form an eqution from this.
4x-26=70
4x=96
x=24
24 x 2 = 48 - 26 = 22
thus, the shortest side is 22cm and the other sides are both 24cm
Answer:
y=70 degrees
Step-by-step explanation:
If 2 angles are complimentary, they add up to 90 degrees.
x+y=90 degrees
x=20 degrees
y=90-20 degrees
y=70 degrees
If that is wrong, try this. Let's say the questions gives us the fact that x is 20 degrees greater than y.
y=x
Substituting x for y, the equation is x+x+20=90
Since y is x, x would also be y, which is 35. then x+20 would be 55.
So y would be 35.
THE ANSWER WOULD BE <u><em>70 DEGREES</em></u>, BUT IF THAT IS WRONG, DO THE SECOND ONE, WHICH IS 35
10 is not a perfect square however 100 is. This is because a square is defined as numbers that are the product of another whole number when multiplied by itself. So, 10x10=100, making 100 a perfect square. However, no number multiplied by itself equals 10, meaning 10 is NOT a perfect square.
