Final answer:
To find the size of angle BAD, we can approximate 29° to (2)(15.56°) which is approximately 31.1°.
Step-by-step explanation:
To find the size of angle BAD, we need to use the given information. From the information provided, we can see that 20₁ is equal to (2)(14.5°) which is 29°. Then, we subtract 0₂ from 0₁, which gives us 30.05° - 14.5° = 15.56°. Finally, we approximate 29° to (2)(15.56°) which is approximately 31.1⁰. Therefore, the size of angle BAD is approximately 31.1°.
