You have to use Pythagorean's theorem to find the missing side measure. 41^2=40^2 + w^2. 1681 = 1600 + w^2. 1681-1600=w^2. 81=w^2 and w = 9. That's an odd triangle, but accurate! Now use the cos definition of cos x = 9/41, and cos x = .2195. Now use the inverse function on your calculator in degree mode to see that the angle x is 77.3 degrees.

Use vector notation to describe the points that lie in the given configuration. (Let s and t be elements of the Reals.)

Blababa [14]

Answer: I(s,t) = {(6s, 5s+6t, 5t)| sER, tER }

Step-by-step explanation:

Given the data in the question;

A vector is in the span of V1 and V2 only if it is a linear combination.

of V1 and V2.

so 'V' is in the span if;

V = SV1 + tV2 [ S and t are real numbers ]

V = [ 6si + 5sj ] + [ 6tj + 5tz]

V = 6s, 5s+6t, 5t

I(s,t) = {(6s, 5s+6t, 5t)| sER, tER }
