Angle ABC= 180-80 = 100
The angle relationship is vertical angles
I don’t know the last one sorry
Answer: A
Step-by-step explanation:
If you put 0 in for x, then you would be dividing by 0. Dividing by 0 is always undefined.
First we have to find the missing angle. And we know that sum of the measurement of angles of a triangle is 180.
So we will get
Now we use sine law, which is
Substituting the values, we will get
The formula of area of triangle, for the given triangle is
B longer slower I think that’s the Correct answer.
