Step-by-step explanation:
Use ratio method
98:2
850:x
so, x = (850 x 2) divided by 98 = 17.3469388
Round it to nearest whole number = 17

Step-by-step explanation:
Answer:
x = <1,5>
y = <-5,1>
Step-by-step explanation:
Let x, y be two vectors in 2D
defined as:
x = <a, b>
y = <c, d>
for x, y to be orthogonal, we know that their dot or scalar product must be zero so,
x . y = 0
<a, b> . <c, d> = 0
a*c + b*d = 0 ------ (A)
Now, consider any four values for a, b, c, and d respectively which satisfy the equation (A)
i.e. I chose (you can choose on your own choice):
a=1, b=5, c=-5, d=1
Verifying Equation (A):
(1)*(5) + (-5)*(1) =0
5 - 5 = 0
0 = 0 (True)
Therefore,
Our vectors x, y are:
x = <1, 5>
y = <-5, 1>
