Explanation:

Step1: Find the measure of ∠ABD

Since ∠A = 60° and assuming triangle ABD is a triangle (though not explicitly stated, but using the angle - sum property of a triangle if we assume it's a straight line - related concept). But more accurately, if we consider the exterior angle or adjacent angles. Wait, another approach: if we assume that ∠ABD is calculated as follows. Wait, no, let's use the property of angles in a triangle - like figure. Wait, actually, if we assume that ∠ABD = 180°-(60° + 80°) is wrong. Wait, no, wait, if we consider that in triangle ABD (assuming AD is a line), no, wait, the key is that ∠CBD can be found using the property of angles. Wait, actually, if we use the property that ∠ABD = 180° - 60°- 80° = 40°, but no, wait, no. Wait, the correct approach:
We know that ∠ADB = 180° - 80°= 100° (linear pair). But no, wait, another way. Let's use the angle - sum property of a triangle. Wait, no, let's use the exterior angle. Wait, actually, we can use the fact that ∠CBD = 180°-(80° + 25°+ 60°) is wrong. Wait, no, the correct formula:
We know that ∠ABD = 180° - 60° - (180° - 80°) is wrong. Wait, the correct way:
We use the property that ∠ABD = 180°- 60° - (180° - 80°) is incorrect. Wait, let's use the following:
We know that ∠ABD = 180°- 60° - (180° - 80°) is wrong. Wait, the correct approach:
