Answer:
b. (√15)/4
Step-by-step explanation:
Since Sin Ф = (opposite side)/Hypotenuse, we have 2 sides of a right triangle.
Use Pythagorean theorem to solve for the missing leg (the adjacent side)
1² + b² = 4²
1 + b² = 16
b² = 15
b = √15
So the adjacent side is √15, so Cos Ф = (√15)/4
Sorry I couldn’t answer but I can ask my friend to answer
Answer:
it's actually none of these.
Step-by-step explanation:
if we divide 15 by 3 we also have to divide 42 by 3. We end up with 5:14. 15 isn't divisible by any number other than 1, 3, 5, and 15.
2 + 8 - x = - 24
10 - x = -24 // Combine like terms
-24 = 10 - x // Switch sides
x - 24 = 10 // add x to both sides
x = 34 // Add 24 to both sides

Answer: x = 34
