solve for the value of e.
(there is a diagram with an angle of 49° and another angle labeled (2e - 7)°)
answer attempt 2 out of 2
e = | input box | submit answer

Explanation:

Step1: Set up the equation

Since the two angles are equal (they are vertical angles), we have \(49=(2e - 7)\).

Step2: Solve for \(e\)

Add \(7\) to both sides of the equation: \(49+7 = 2e-7 + 7\), which simplifies to \(56=2e\).
Divide both sides by \(2\): \(\frac{56}{2}=\frac{2e}{2}\), so \(e = 28\).

Answer:

\(28\)
