How would you prove that the triangle below is equilateral? A. Shows all angles to be congruent

B. Show all sides to be congruent

C. Show at least two sides to be congruent

D. Show two sides are of equal measure

Please help me with this I need help

B. show all sides are congruent

Step-by-step explanation:

approximately 69.93

Step-by-step explanation:

So the square root of 8 is about 2.8,

the square root of 12 is about 3.5, '

add those and you should get 6.3

since your multiplying, you should solve for the other expression in the parenthesis as well

the square root of 48 is equal to about 6.9

the square root of 18 is around 4.2,

add those and you should get 11.1,

When you multiply 11.1 and 6.3, you should wind up with 69.93, since we rounded a lot, this is only an approximation :)

Thank you for the generous amount of points btw :)
