Find Angle BAD in Triangle: Given Angles 86°, 28°, and 122°

First, let's find the value of angle B.

Since the sum of angles in a triangle is equal to 180, the formula is:

$180-86-28=66$

Now let's look at angle ADB, we can calculate its value since we are given angle ADC.

$180-122=58$

Now we can calculate angle BAD:

$180-66-58=56$
