Question

coordinate planes II help!!

Answer 1

the first is a right triangle, use the side^2+side^2 = slant^2
to get slant length

pythagorean theorem

8^2 + 6^2 = x^2

Answer 2

100?

Answer 3

yes 100 = x^2, need to finish for the x value, that is the missing side

Answer 4

parallelograms have a couple special properties

The figure has opposite angles as the same measure, this can be proven with other steps, but the answer is to just state that

Answer 5

so 100 is the answer ?

Answer 6

no square root of 100, or 10

Answer 7

oh okay so 10 what about the other question?

Answer 8

you solve 100 = x^2, by taking the square root
