Answer:
ANGLE K IS 75 DEGREES
All the interior angles of a triangle ADD up to 180 degrees
lets add the angles!
6x-11+8x-29+3x-1
add like terms. all the x terms add up and all the constants as well
8x+6x+3x = 17x
-29-1-11 = -41
17x-41= 180 (-41 + 41 = 0 we do this to remove -41 from the left side of the equation to isolate x)
41+180 = 221
17x=221
221/17 = 13
x=13
so..
8 * 13 - 29 is the angle..
8*13 = 104
and 104-29 = 75
Angle K is 75 degrees! hope that helps..

Answer:
0
Step-by-step explanation:
x2 +4x-21=0. solve for x


(2x-10)/4 = 3x
2x - 10 = 12x
10x = -10
x = -1
