Show that the plane and line with the given equations intersect, and then find the acute angle of intersection between them. (give the angle in degrees and round to one decimal place.) the plane given by x + y + 2z = 0 and the line given by x = 6 + t y = 1 − 2t z = 3 + t. substituting the parametric equations for the line into the equation for the plane and solving for t gives t = correct: your answer is correct. , so that the plane and the line intersect at the point (x, y, z) = correct: your answer is correct. what is the acute angle of intersection? θ = °

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
