The best approach to this is to use the law of cosine which is stated as
c2 = a2 + b2 â’ 2ab cos(C)
distance a=176.27; distance b=222.34; angle C=38.59; distance c is the missing value.
Hence c²=176.27²+222.34² -2*176.27*222.34cos38.59°= 138.71 miles
Answer:
the x is 3 and the y is -3
Step-by-step explanation:
Answer:
17x + 37
Step-by-step explanation:
looked it up
I'm assuming you meant 1.5 × 10⁴. Remember, when we write in standard form, you need to use ^ to denote it's 'to the power of'. So it would be 1.5 × 10^4.
I'm also assuming you meant in decimal form, because that's already in standard form.
However, the answer is 15,000. This is because you lose one zero when multiplying a decimal with one number after it. For each number after the decimal, you take off a zero. Therefore, the end number is 15,000.
Answer:
x = 
Step-by-step explanation:
In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we took away 17 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.
- 2x + 4 = -6x - 17
→ Add - 6x to both sides to bring all the 'x' coefficients to one side
4x + 4 = -17
→ Minus 4 from both sides to bring all the integers to the other side
4x = -21
→ Divide both sides by 4 to isolate x
x =
