In getting the area of and equilateral triangle, you must first consider that all of its sides are congruent and that is 3 inches, so the formula in getting the area is height form its base so in getting its height you must use the pythagorean theorem by dividing the triangle so the hypotenuse of it is 3 and the base of 1.5inches, so the height is 4.77 inches then the area is 7.15 sqr.inch
If you had a pic I could answer
Answer:
5%
Step-by-step explanation:
fraction empty = empty / total
= 4/ (76+4)
= 4/80
=1/20
Changing to a percent
1/2 *5/5 = 5/100 = 5%
The answer is: [A]: "right [triangle]" .

Given: Side lengths:
________________________________________________
" <span>24 in., 32 in., and 40 in " ;
________________________________________________
Divide each side length by "8" ;
</span><span>
24 in. / 8 = 3 in. ;
32 in. / 8 = 4 in. ; and
40 in. / 8 = 5 in. .
_________________________________________________
3 in . , 4, in, 5 in. ; is a "right triangle" ;
since: 3</span>² + 4² = 5² ;
→ 9 + 16 = 25 ;
according to the Pythagorean theorem: " a² + b² = c² " .
