2. it can't have three because one of them is a right triangle do D doesn't add up. It can't have 0 because an obtuse angle plus a right angle would go over 180 degrees. So, the most it can have is 2 acute for example 90(right angle) 30(acute) and 60 (acute) is a possible answer. Also, a right angle can only have two acute angles since an obtuse angle would put it over 180 which was already stated
Given the equation;
To solve, let us multiply through by the least common multiple of the the denominator of the three fractions wich is 24;
(9 - 7 × 3 + 4)²
(9 - 21 + 4)²
(9 - 17)²
(-12)²
144
158.71 rounded to the nearest ten dollars would be $160.00
then to estimate 10% since 10% starts with a 1, just remove the zero from both numbers
so 160 becomes 16
the tip would be $16
Answer:
Step-by-step explanation:
Hello.
to find the volume of a sphere we must know its radius,
we don't know the radius but we have the area
Now, replacing this value in the volume equation
have a great day
