Answer:
For the first picture, I think it is C and the second one should be A.
Step-by-step explanation:
You use vertical lines and if it hits it multiple times it is not a function. Like if it hits two dots or something it is not a function. I hope that make sense, let me know if it doesn't.
Answer:
#1) Angle measure of B
The angles in a triangle should add up to 180. Since we know the other two angle measures, we can subtract it from 180. (180-45-15= Angle B)
Angle B= 120
#2) Length of segment BC
I would use the Law of Sines. So, sin120/200 = sin45/BC
Then cross multiply and divide.
Segment BC= 163.3
#3) Length of Segment BA
Again, I would use the Law of Sines. Same process, sin120/200 = sin15/BA
Segment BA= 59.8
Answer:
70
Step-by-step explanation:
triangle is 180deg in total thus,
