Vertical angles i believe is the right answer to this problem
Yes. This is because you take the two fractions and find a common denominator. The common denominator being 12 so then you have 39/12 and 8/12. If each scarf she makes is 8/12 yards of fabric she should have enough to make two scarves.
Vertical angles are always congruent
Make an equation
3x - 47 = 2x + 8
3x = 2x + 55
Subtract 2x
x = 55
Solution: B. X = 55
Answer:68600m
Step-by-step explanation:98 meters to cm is 9800 then times it by 7 you get 68600
Answer:
73.21 m
71.68°
Step-by-step explanation:
Like the question has stated, we're to solve this using Pythagoras theorem.
Pythagoras theorem states that
opp² + adj² = hyp²
From the question, we're asked to find the hypotenuse, being given the opposite side and the adjacent. The opposite side is the center of the Ferris wheel above the ground, and that is 69.5 m. While the adjacent is the distance of the second anchor.
Succinctly put, we have
69.5² + 23² = hyp²
4830.25 + 529 = hyp²
hyp² = 5359.25
hyp = √5359.25
hyp = 73.21 meters.
Therefore, the length of the cable is 73.21 meters long.
To get the angle, we use the formula
Sin Φ = opp/hyp
Sin Φ = 69.5 / 73.21
Sin Φ = 0.9493
Φ = sin^-1 0.9493
Φ = 71.68°
Therefore, the angle of elevation to the center of the Ferris wheel is 71.68°
