Answer:
k = 140°
Step-by-step explanation:
The sum of the interior angles of any triangle = 180°.
64° + 76° + x = 180°
x = 40°
40° + k = 180° because they are supplementary angles
k = 140°
1)11.78
2)3x-2
4)yes becouse the total will be 3.27
6)x=14
7)x=4
the last one )y=12x
Angle 2 and 5 are alternate interior angle and they are congruent. That means that m <5= 35°.
