Sagot :

Answer:

its 100

Step-by-step explanation:

The question is asking what is ∠ABD, you  have to look at when A=0 on the projector, so if you follow along the 0° from A, when it reaches D, the project reads 100°

no guessing here,

you know 80° cannot be correct because this angel is obtuse and not acute

which means greater that 90°
