Which one, 1 or 2?
OpenStudy (studygurl14):
Please don't spam @arturos
OpenStudy (anonymous):
I want to know is 1 right? but I need help on 2
OpenStudy (anonymous):
ok so for 2 you know that angle b is 50deg
and it is safe to assume that angle c is 90deg correct?
OpenStudy (anonymous):
im pretty sure 1 is right

and the sum of all angles(A+B+C)=180 because its a triangle
OpenStudy (anonymous):
Is #1 right first?
OpenStudy (studygurl14):
Yes, it is.
OpenStudy (anonymous):
are there any answers for question two that you would immediately cross out?
OpenStudy (anonymous):
Thank you now I need help with #2

so in the end the answer for 2 is dragons
OpenStudy (studygurl14):
For number two, focus on the triangle part. Because line AD is tangent to the cirlce, it forms a right angle.
OpenStudy (studygurl14):
If m<ABC = 50, and m<ACB = 90, and all triangles' angles add up to 180...
OpenStudy (anonymous):
So it will be 180?
OpenStudy (studygurl14):
No, all the angle measures when added together equal 180.

So,
m<ABC + m<ACB + m<BAC = 180
If m<ABC = 50 and m<ACB = 90, what does m<BAC equal?
OpenStudy (anonymous):
90 or 140
OpenStudy (studygurl14):
No, plug in the values...
m<ABC + m<ACB + m<BAC = 180
50 + 90 + m<BAC = 180
m<BAC = 180 - 50 - 90 = ?
OpenStudy (anonymous):
40
OpenStudy (studygurl14):
correct.
