Answers:
scalene (column 1)
right triangle (column 2)
==============================================
Explanation:
The lack of tickmarks tells us indirectly that none of the sides are equal to one another. So all three sides are different lengths. Therefore, the triangle is scalene. This rules out "equilateral" and "isosceles".
The small square marker indicates we have right angle, aka 90 degree angle. In turn, it leads to the fact we have a right triangle. This rules out "acute" because acute triangles have all three angles smaller than 90. We can also rule out "obtuse" because obtuse triangles have one angle larger than 90.
In short, this triangle is both scalene and a right triangle. We can call it a right scalene triangle, or a right triangle that is scalene.
Slope =3
process--
=3
Point-slope form is 3x-y-6=0 (using the first set of points, (1,-3) )
process--
y-9=3(x-5)
y-9=3x-15
y=3x-15+9
y=3x-6
<u><em>3x-y-6=0</em></u>
Answer:
Finding the missing side of a right triangle is a pretty simple matter if two sides are known. One of the more famous mathematical formulas is a2 +b2 = c2 a 2 + b 2 = c 2, which is known as the Pythagorean Theorem. The theorem states that the hypotenuse of a right triangle can be easily calculated from the lengths of the sides.
Step-by-step explanation:
To get an expression relating to x you need to have x alone on one side of your equation. ie x =
<span>Try this: </span>
<span>rx - st = r </span>
<span>remove st from the rx side </span>
<span>rx = r + st </span>
<span>now divide by r </span>
<span>x = (r + st)/r </span>
<span>You now have your expression relating to x</span>
When you're finding a fraction in the simplest form, you have to find a common multiple, and the best way to do this is to list the multiples.
17- 1,17
34- 1,2,17,34.
In this case, the common multiple is 17, therefore, you need to divide both sides by 17. 17/17= 1. 34/17=2.
Therefore, 17/34 in the simplest form is 1/2.
Hope this helps :)
