Question

if ( mangle chf = 103^{circ}), then what is ( mangle fhd)?

Explanation:

Step1: Use the property of supplementary angles

Supplementary angles add up to \(180^{\circ}\). \(\angle CHF\) and \(\angle FHD\) are supplementary.
So, \(m\angle CHF + m\angle FHD=180^{\circ}\)

Step2: Solve for \(m\angle FHD\)

Given \(m\angle CHF = 103^{\circ}\), then \(m\angle FHD=180^{\circ}-m\angle CHF\)
Substitute \(m\angle CHF = 103^{\circ}\) into the equation: \(m\angle FHD = 180^{\circ}- 103^{\circ}\)
\(m\angle FHD=77^{\circ}\)

Answer:

\(77\)
