Answer:
-8/6 is equivalent to the -8.(1/6).
Answer:
A^2 + B^2 = C^2
6^2 + 14^2=c^2
36+196=C^2
232=c^2
square root of 232= c
therefore c is equal to 15,23

Answer:
<h2>
50°, 60°, 70° (the second answer)</h2>
Step-by-step explanation:
The sum of the angles in a triangle = 180°
We can use the equation:
2x + 80 + 25 - 5x + 6x + 90 = 180
Combine like-terms:
2x + 6x - 5x = 3x
80 + 25 + 90 = 195
195 + 3x = 180
Subtract 195 from both sides:
3x = -15
Divide both sides by -3 to isolate x:
x = -5
Now that you've solved for x, you can replace x with -5 in the equation for each angle.
2(-5) + 80 = 70°
6(-5) + 90 = 60°
25 - 5(-5) = 50°
