Set up two fractions:
8/x and 3/5
Set them equal to each other and cross multiply to get:
8*5 = 3x
40 = 3x
13.3 = x or 13 and 1/3 feet tall.
To solve for X you must get x by itself so let's get started
-4x+13=6x-7
subtract 13 from both sides
-4x=6x-20
subtract 6x from both sides
-10x=-20
divide both sides by -10
x=2
to check if this is correct plug in x into original equation
-4 (2)+13=6 (2)-7
-8+13=12-7
5=5
answer x=2 holds true :)
<span>The correct option is: (C) a⊥b, by Perpendicular Transversal Theorem
Explanation:
Perpendicular Transversal Theorem states that in a plane, if a line is perpendicular to one of two parallel lines, then it is perpendicular to the other line also.
As the line b is perpendicular to the line c and the line c is parallel to the line a, hence the line a is perpendicular to the line b. Therefore, the correct option is (C) a⊥b, by Perpendicular Transversal Theorem
