What is the measure of

Step-by-step explanation:

From your choices, it looks like you want m<A

Solution

<C = 46°                      The triangle is isosceles. The two marked sides are equal.

<A + <B + <C = 180l    All triangles have interior angles = 180

<A + 46 + 46 = 180     Combine

<A + 92 = 180              Subtract 92

<A = 180 - 92

<A = 88
