Answer:
43.0°
Step-by-step explanation:
cos∅=adj/hyp
cos∅=60/82
∅=cos-1 60/82
∅=cos-1 0.731707317073
∅=42.97028393174°
Round: 43.0°
A(-3,5) to B(8,1)
That makes a right triangle 8 - -3 = 11 in the x direction, 5 - 1 = 4 in the y direction.
d² = (8 - -3)² + (1 - 5)² = 11² + (-4)² = 121 + 25 = 146
d = √146 = 12.083045973594572
Answer: 12.1
Answer:
3
Step-by-step explanation:
In order to have a perfect square you have to have at least two prime factors, and since three is quite clearly not in a pair, the answer is three.
2/3 + 3/4 = 8/12 + 9/12 = 17/12 = 1 5/12
1 + 5/12 = 12/12 + 5/12 = 17/12 = 1 5/12
2/3 + 3/4 = 1 + 5/12
