Question

solve for x.
(7x - 3)°
81°
x =
submit

Explanation:

Step1: Identify angle relationship

The 81° angle and (7x-3)° are corresponding angles (since lines are parallel), so they are equal.

Step2: Set up equation

$$7x - 3 = 81$$

Step3: Solve for x

Add 3 to both sides: $$7x = 84$$
Divide by 7: $$x = 12$$

Answer:

12
