Answer:
Option D
Step-by-step explanation:
By applying cosine rule in the given triangle,
a² = b² + c² - 2b.c.cos(m∠A)
By substituting values in the formula,
9² = 10² + c² - 2(10)(c)cos(15)°
81 = 100 + c² - 19.32c
c² - 19.31c + 19 = 0
By quadratic formula,
c = 
= 
= 1.08, 18.27
≈ 1.1, 18.3
Therefore, Option D will be the answer.
2x+y=1 is in standard form so we will convert it to slope int form by subtracting 2x
y=-2x+1
the line we are finding the equation for is PARALLEL to this line here so the slope is the same
for the line’s equation we will put it in point slope form. y-y1=m(x-x1)
y-2=-2(x+2) is the answer!
Answer:
A
Step-by-step explanation:
Both vectors have the same length/ magnitude, so they are equal and since they are going the same direction, they're also parallel and won't touch.
