Answer:
A.) 0.9cm, 1.2cm, 1.5cm
Step-by-step explanation:
The side ratios of the offered answers are ...
A — 3:4:5 . . . . . . obviously a right triangle
B — 3:5:5 . . . . . . isosceles, but not a right triangle
C — 3:4:6 . . . . . . an obtuse triangle
D — 3:2:5 . . . . . . not even a triangle (just a line segment)

<em>Comment on 3:4:5</em>
This set of small integers appears often in problems involving right triangles. It is the smallest "Pythagorean triple" — a set of integers that satisfies the relationship of the Pythagorean theorem — and it is the only Pythagorean triple that is an arithmetic sequence (differences between the numbers are the same).
When you see a triangle with sides in these ratios, you know it is a right triangle. When you see a right triangle with two of the sides having a ratio of 3:4, 3:5, or 4:5 (where "5" is the hypotenuse), then you know the length of the remaining side.
Answer:
well the first one is x^3 y^2 z 7root x^2 z
Answer:
x = 3 x = -5
Step-by-step explanation:
2|x+1|=8
Divide each side by 2
2/2|x+1|=8/2
|x+1| = 4
There are two solutions to an absolute value, one positive and one negative
x+1 = 4 x+1 = -4
Subtract 1 from each side
x+1 -1 = 4-1 x+1-1 = -4-1
x = 3 x = -5
