Question

find t. (4t + 18)°

Explanation:

Step1: Use property of parallel lines and right angle

When two lines are parallel and cut by a transversal, and there is a right - angle formation. The angle \((4t + 18)^{\circ}\) is a right angle. So, \(4t+18 = 90\).

Step2: Solve the equation for \(t\)

Subtract \(18\) from both sides of the equation:
\(4t+18-18=90 - 18\)
\(4t=72\)
Divide both sides by \(4\):
\(t=\frac{72}{4}\)

Answer:

\(t = 18\)
