Let’s say we have 1 and 3.
3-1=2
Thats an even number, so false, but lets check some more just to be sure:
27-3=24 (even)
13-5=8 (even)
75-3=72 (even)
So, the answer is false.
Equailateral means that base=40mm
solve for height
split the triangle in half with a line perpendicular to the base
now you have 2 right triangles with base 40/2=20 and hypotonuse 40
solve for height or the other side
use pythagorean theorem
a^2+b^2=c^2
20^2+b^2=40^2
400+b^2=1600
subtract 400 fromb oth sides
b^2=1200
square root boht sides
b=√1200=20√3
the height =20√3
area of triangle=1/2base times height
base=40
height=20√3
1/2 times 40 times 20√3=20 times 20√3=400√3
the area is 400√3 mm^2
Answer:
36
Step-by-step explanation:
A (base) 6
B (Base) 12
H (height) 4
Answer:
<em>Perimeter = 6x + 5.</em>
Step-by-step explanation:
The perimeter is the sum of the three sides.
Perimeter = 3x - 2 + (-5x) + 8x + 7
= 3x - 2 - 5x + 8x + 7
= 3x - 5x + 8x - 2 + 7
= 6x + 5.
