174/29 = 6 times the difference
17*6 = 102
12*6= 72
34*6 =204
15*6 = 90
so the answer is A
If x approach infinity then (x² + 1)/(2x² +1) = 1/2 then lim as x approach infinity
lim y = arccos 1/2 = 1.047

Answer:
61°
Step-by-step explanation:
Since the angles make up a full circle which is 360°, deduct all the degrees with numbers from 360°
360 - 65 - 50 - 62 = 183
x + 2x = 3 x
3x = 183
x = 183 ÷ 3 = 61
