x = 80
the sum of the angles round a point is 360°
the 3 angles here must sum to 360°
3x + x - 27 + 67 = 360
4x + 40 = 360
subtract 40 from both sides.
4x = 360 - 40 = 320
divide both sides by 4
x =
= 80
thus the 3 angles are 67°, 240° and 53°
Answer:
The answer for the question is D. 1/x^8
Your answer is 54, the drawing is a bit wrong because I did the prime factor tree of 54 wrong, so you'd do 2 × 3 × 3 × 3 which is 54.
A. -4
b. -10
c. 10
d. -21
e. 2
f. 46
