What are the most obtuse angle you can create in a triangle?
Contact [7]
The obtuse interior angle in triangle can reach to 179.9999999.... °.
Because once it hits 180°, the angle becomes a straight line and it is not possible in a triangle.

Could someone please help with this?

Answer:

  5.  88.0°

  6.  13.0°

  7.  52.4°

  8.  117.8°

Step-by-step explanation:

For angle A between sides b and c, the law of cosines formula can be solved to find the angle as ...

  A = arccos((b² +c² -a²)/(2bc))

When calculations are repetitive, I find a spreadsheet useful. It doesn't mind doing the same thing over and over, and it usually makes fewer mistakes.

Here, the side opposite x° is put in column 'a', so angle A is the value of x. The order of the other two sides is irrelevant.

<em>Additional comment</em>

The spreadsheet ACOS function returns the angle in radians. The DEGREES function must be used to convert it to degrees. The formula for the first problem is shown here:

  =degrees(ACOS((C3^2+D3^2-B3^2)/(2*C3*D3)))

As you can probably tell from the formula, side 'a' is listed in column B of the spreadsheet.

The spreadsheet rounds the results. This means the angle total is sometimes 179.9 and sometimes 180.1 when we expect the sum of angles to be 180.0.

I will give brainelest but i need help on the graph
const2013 [10]

Answer:

1)   (6,2) (9,2) (3,8) (3,5)

2)   (2,-5) (5,-5) (-1,-11) (-1,-8)

Step-by-step explanation:

For the first question, your reflecting over the x-axis into quadrant I, so you just need to make all the coordinates positive.  The numbers stay the same - you just get rid of the negative signs.  (6,2) (9,2) (3,8) (3,5)

For the second problem, you subtract 4 from the x-value, and 3 from the y-value.

(6,-2) becomes (2,-5)

(9,-2) becomes (5,-5)

(3,-8) becomes (-1,-11)

(3,-5)  becomes (-1,-8)
