Answer:
d = 41
Step-by-step explanation:
if the two lines are parallel, then 113 and 2x-5 are supplementary, which means that they add up to 180.
So:
113 + 2x - 5 = 180 =>
2x = 72
x = 36
Next step, we have three angles in the triangle that should add up to 180:
2x-5 + 2x + d = 180 with x=36
d = 180 - 139 = 41
so the angles are 72, 67 and 41
You just divide both sides by 7:
7k/7 = 77/7
k = 77/7
k = 11
Final answer: k = 11

Answer:
X = 12
Step-by-step explanation:
If the angle depicted on top is the angle for the inside angle in the triangle, we can find x easily. a line is 180 degrees so we can do 180-151 for the right inside angle. that's 29. we can do 5x+3+9x-20+29 = 180. 14x+12=180. 14x = 180-12. 14x = 168. 168/14 = 12
