Answer:
x=19
Step-by-step explanation:
In order to solve for x, we want to add the equations to equal 180.
6x+12+3x-3=180
9x+9=180
9x=171
x=19
To classify the angle of a triangle (acute, obtuse, or right), you can use slope formula to see if the slopes are perpendicular. If so, it is a right triangle. The distance formula can be applied to figure out whether the triangle is isosceles, equilateral, or scalene. if the triangle is isosceles, then two of the sides will be the same length and one side will be of a different length. If the triangle is equilateral, then all sides will be of the same length. If the triangle is scalene, then all side will be of different lengths.
Rate is ...
... r = d/t
Multiply both sides of the equation by time to find distance.
... rt = d
The equation for d is ...
... d = r·t
Answer:
2. x + 98 + 50 = 180
3. x = 32°
Step-by-step explanation:
<em>hey there,</em>
< 2. We know that there are 180 degrees in every triangle, and every triangle has only 3 angles. So when you add up those 3 angles, it will ALWAYS equal 180! And since we do not know one of the angles, we will just put the value of that angle as "x" into the equation.
3. Here, you should be able to find x! x = (180-(98+50)) = 32
The final answer is 32 degrees. >
