First, find the value of x. Note that the angles x, 0.5x and 3x sum up to 4.5x, and that this sum has the value 180 degrees. Solving this equation for x, we get x = 40 degrees.
Now, 0.5x and 0.5y are vertical angles, and thus x = y. So, with x being 40 degrees, y = 40 degrees.
2) given (because they already marked that on the picture)
3) N is vertically opposite to the angle above => N equals the angles above
JK is parallel to ML
JN = NL
4) KJN and MLN have alternate angles => equal
5) JN = NL
angle JNK = angle LNM
angle KJN = angle MLN
Answer:
-2pi/3
Step-by-step explanation:
y = 2 cos 3(x + 2π∕3) +1
y = A sin(B(x + C)) + D
amplitude is A
period is 2π/B
phase shift is C (positive is to the left)
vertical shift is D
We have a shift to the left of 2 pi /3
Answer:
20% tip is $3.97, add that to 18.97 and you get $22.76, then add 8.25 and you get $31.01
Answer:
C. 726
Step-by-step explanation:
9196-1936=7260 and take away the 0 so your answer will be 726
