Question

5.5.3 quiz: rhombi and squares given that abcd is a rhombus, what is the value of x? a. 28 b. 56 c. 48.5 d. 18 e. 36 f. cannot be determined

Explanation:

Step1: Recall rhombus property

In a rhombus, the diagonals bisect the angles of the rhombus. So, the angle \((5x - 18)^{\circ}\) and \(x^{\circ}\) are equal.
\[5x-18=x\]

Step2: Solve the equation

Subtract \(x\) from both sides: \(5x - x-18=x - x\), which simplifies to \(4x-18 = 0\). Then add 18 to both sides: \(4x-18 + 18=0 + 18\), getting \(4x=18\). Divide both sides by 4: \(x=\frac{18}{4}= 4.5\) (This is wrong. Let's correct. The correct property is that adjacent - angles of a rhombus are supplementary and the diagonals are perpendicular bisectors. The correct way is that the two angles shown are equal because the diagonal of a rhombus bisects the angles of the rhombus. So \(5x-18=x\)).
\[5x - x=18\]
