Find the value of x xx in the triangle shown below. x x 8 8 9 9 Choose 1 Choose 1 (Choice A) A x = 72 x= 72 x, equals, square root of, 72, end square root (Choice B) B x = 3 x=3x, equals, 3 (Choice C) C x = 4 x=4x, equals, 4 (Choice D) D x = 17 x= 17 x, equals, square root of, 17, end square root

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
