What are the answers to part A and part B?

Answer:
Step-by-step explanation:
a. Sum of angles in a triangle is 180°
:- w° + 67° + <Y = 180°
<Y = 180° - 67° - w°
<Y = 113° + w°
b. Sum of angles in a triangle is 180°
:- <I + <K + <Y = 180°
33° + 67° + 14d - 19° = 180°
14d = (180- 33- 67 + 19)°
14d = 99°
d = 99/14
d = 7.1°
