What is the classification of the triangle by its angle and by its sides?

▪︎In this triangle all angles are less than 90°. We know that angles of a triangle which are less than 90° in measure will be called acute angles. Thus, this triangle is an acute angle when we classify it by it's angles.

▪︎All sides of this triangle are equal. We know that when all sides of a triangle are equal, it is to be called an equilateral triangle. Thus, this triangle is an equilateral triangle when we classify it by it's sides.

Therefore, the correct option is (A) acute, equilateral

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
