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
K - 45 = 18
k = 18 + 45 = 63
Answer:
Step-by-step explanation:
i don't know just want points
Answer:
False
Step-by-step explanation:
The angles are the same, but we know nothing about the sides
For triangles to be congruent, the sides have to be the same length
Since we don't have information about the sides, we do not know if they are congruent.
