Answer:
The answer is
One: 28, 29, 30
Two: 75,77
Step-by-step explanation:
One
Let the three numbers be (x - 1) , x , and x + 1
(x - 1) + x + (x +1 ) - 12 = 75 Remove the brackets
x - 1 + x + x + 1 - 12 = 75 Combine the like terms on the left
3x - 12 = 75 Add 12 to both sides
3x = 75 + 12
3x = 87 Divide by 3
x = 87/3
x = 29
Two
Let the first odd number = 2x -1
Let the second odd number = 2x + 1
2x - 1 + 2x + 1 + 18 = 170 Combine like terms on the left.
4x + 18 = 170 Subtract 18 from both sides.
4x = 170 - 18 Combine like terms on the right
4x = 152 Divide by 4
4x/4 = 152/4
x = 38
2 * 38 - 1 = 75
2 * 38 + 1 = 77
As you can probably tell, this is a 30, 60, 90 triangle. That means the degree measures are 30, 60, and 90. These are special triangles. For every 30, 60, 90 triangle in the world, the shorter leg (in your case, x) is ALWAYS two times shorter than the hypotenuse (6). 6/2=3, so x=3. Also, the longer leg for a 30, 60, 90 triangle is always equal to the shorter leg times the square root of 3. So, 3 times the square root of 3 is about 5.2. So, y=5.2. Hope it helps!
