Given triangleABC~triangleDEF

m<A=62 degrees
m<E=13 degrees
what is the measures of angle C?

1 answer

Since triangles \( ABC \) and \( DEF \) are similar (denoted as \( ABC \sim DEF \)), the corresponding angles are equal. This means:

\[ m<A = m<D, \quad m<B = m<E, \quad m<C = m<F \]

We are given that \( m<A = 62^\circ \) and \( m<E = 13^\circ \).

Since \( m<B \) corresponds to \( m<E \), we can find \( m<B \): \[ m<B = m<E = 13^\circ \]

Now, we can use the fact that the sum of the angles in a triangle is \( 180^\circ \) to find \( m<C \): \[ m<A + m<B + m<C = 180^\circ \] \[ 62^\circ + 13^\circ + m<C = 180^\circ \]

Calculating the left side: \[ 75^\circ + m<C = 180^\circ \]

Now, solving for \( m<C \): \[ m<C = 180^\circ - 75^\circ = 105^\circ \]

Thus, the measure of angle \( C \) is: \[ \boxed{105^\circ} \]
