Answer:
54 cm
Step-by-step explanation:
The area (A) of an equilateral triangle is
A =
( s is the side length ) then
= 81
( multiply both sides by 4 to clear the fraction )
s²
= 324
( divide both sides by
)
s² = 324 ( take the square root of both sides )
s =
= 18
Thus
perimeter = 3 × 18 = 54 cm
Answer:
58 degrees
Step-by-step explanation:
(x+45)+(x+66)=95
2x+45+66=95
2x+111=95
2x=95-111
2x=-16
x=-16/2
x=-8
x+66=-8+66=58
