What's your question?

OpenStudy (studygurl14):

@rffsdf You there?

OpenStudy (anonymous):

Yes hold on the question is coming

OpenStudy (anonymous):

OpenStudy (anonymous):

the answer is dragons

OpenStudy (studygurl14):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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.

OpenStudy (studygurl14):

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.

OpenStudy (anonymous):

Thank you :)
