Answer:
26, 68 and 84
Step-by-step explanation:
Let the angle that is three times smaller than another be X.
Since the angle sum of a triangle is 180 degrees, we can form the following equation:
X + 3X + (3X- 16) = 180
Now we can simplify this equation:
7X - 16 = 180
7X = 196 (add 16 to both sides)
X = 196/7
X = 28
Therefore, the smallest angle is 28 degrees.
And from here we can figure out the other angles as they are 3x28 and 3x28 - 16.
So the three angles are 28 degrees, (3x28-16) 68 degrees, and (3x28) 84 degrees.
(3/4)+(1/5(1/4)
As my thinking, this is the answer...

A, D, E and F are all true statements.
When looking for congruence in these type of problems, you have to look for the order of the letters in the original listing. Since they are listed LMN and PQR, this means we have to focus on the placement of those letters. Since L is the first listed in the sequence, it is congruent with P, which is also listed first. M is congruent with Q since they are both in the middle, and N and R are congruent since they are both at the end.
Now to find true statements, you need to make sure everything matches up in the statement.
Let's take A for instance. It states that MN = QR. Now we know M is in the middle and N is at the end. Since Q is in the middle and R is at the end, they match and are therefore true.
That would be a right triangle.
