Answer:
Step-by-step explanation:
The angles <JKL, <EKL, and <JKE form a full angle which means their sum is equal to 360:
134 + 21x + 6 + 5x = 360 add like terms
140 + 26x = 360 subtract 140 from both sides
26x = 220 divide both sides by 26
x = 8.4 approximately
to find the angle m<JKL replace x with the value we found.
This is a <em>right triangle</em>

Answer:
He drove 63 miles in one day
Step-by-step explanation:
151.2/2.4=63
1) subtract the accepted value from the experimental value.
2) Take the absolute value ofvstep 1
3) Divide the answer by accepted value
4) Maltiply that answer by 100 and add the % symbol to express the answer as a percentage.
Unsure of what you mean by "reference number."
I do recognize that 11pi/9 is in quadrant III. I suspect that the so-called "reference number" is the acute angle between the end ray of 11pi/9 and pi, or, in more easily comparable numbers, between 9pi/9 and 11pi/9.
That difference is 2pi/9.
