Left Side Triangle: x = 142°
Top Middle Triangle: x = 136°
Bottom Middle Triangle: x = 26°
Right Side Triangle: x = 54°
Answer:
156.37°
Step-by-step explanation:
We solve this above question, using Cosine rule which is given as:
Cos C = a² + b² - c²/2ab
Let the Angle be represented as: x
Cos x = 310² + 200² - 150²/2 × 310 × 200
x = arc cos [ 310² + 200² - 150²/2 × 310 × 200]
x = 23.63°
The angle, in degrees, that he must turn through to head straight for Island B is given as:
180° - 23.63°
= 156.37°
Answer:
$27.99
Step-by-step explanation:
100/7.25% sales tax = 1.54 x 13.7931034483 = 21.2413793104
We did the example to prove that when accounting for fixed tax the price will be higher once tax of same percentage amount applied.
This proves 1.75% more in interest is a far lower price ($6.56 less)
Where we compare the price set for 5.5 as asked in the question.
100/5.5% sales tax = 1.54 x 18.181818181 =27.9999999987
=$27.99
We do not round up or down repeating numbers.
Answer: 2
Step-by-step explanation:
That the variable Z is directly proportional to X and inversely proportional to Y means Z = A (X/Y)
=> A = Z* Y / X
=> 9.5 * 6 / 3 = Z * 12 /8
=> Z = 9.5 * 8 * 6 / (3 * 12) = 12.67
Answer: 12.67
