Question

look at the diagram.
which equation can be used to solve for x?
18x = 90
8x + 10 = 180
18x = 180
8x + 10 = 90
solve for x.
x =

Explanation:

Step1: Analyze the angle relationship

Since the two angles \(10^{\circ}\) and \((8x)^{\circ}\) form a right - angle (\(90^{\circ}\)), we can use the equation \(10 + 8x=90\).

Step2: Solve the equation for \(x\)

Subtract \(10\) from both sides of the equation \(8x + 10=90\):
\(8x+10 - 10=90 - 10\)
\(8x=80\)
Divide both sides by \(8\):
\(x=\frac{80}{8}\)

Answer:

\(x = 10\)
