Question

Find the value of b
C=126*
B=
B is at 90*

Answer 1

She is at 180° angle B is a 90° angle

Answer 2

To clarify your request, it seems like you're referring to a right triangle with angle \( C \) being \( 126^\circ \) and angle \( B \) being \( 90^\circ \). However, in a triangle, the sum of the angles must equal \( 180^\circ \). Therefore, angle \( A \) can be calculated as follows:

\[
A + B + C = 180^\circ
\]
\[
A + 90^\circ + 126^\circ = 180^\circ
\]
\[
A + 216^\circ = 180^\circ
\]
\[
A = 180^\circ - 216^\circ
\]
\[
A = -36^\circ
\]

This result suggests an inconsistency, as angle \( A \) cannot be negative in a triangle.

### Conclusion:
- A triangle cannot have angles measuring more than \( 180^\circ \) in total. Given \( C = 126^\circ \) and \( B = 90^\circ \), angle \( A \) would indeed be negative, which is impossible. Hence, please recheck or clarify the angle values you gave.

Answer 3

Thank you for the clarification! It seems like we're dealing with a scenario involving angles, perhaps in a triangle or another geometric figure.

If you’re stating:
- Angle \( C = 180^\circ \)
- Angle \( B = 90^\circ \)

Then we can deduce that this configuration is not possible for a triangle because the sum of angles in a triangle must equal \( 180^\circ \).

To summarize the situation:
1. In a triangle, the sum of all three angles (A + B + C) must equal 180°.
2. If \( B = 90° \) and \( C = 180° \), that already exceeds 180°.

Assuming instead that you meant to say \( B = 90^\circ \) and some other angle \( A \) needs to be found, with the total angles summing to 180°:

1. Let’s denote the third angle as \( A \).
2. The relationship is: \( A + B + C = 180^\circ \).

If \( B = 90^\circ \), we can’t have \( C \) also equal to \( 180^\circ \) because \( B \) already occupies half of the total sum of angles in a triangle.

If you're looking for a specific situation involving angles \( B \) and \( C \), could you please clarify how \( C \) and \( B \) relate or what value you want to determine? If there is a different scenario (like in a quadrilateral), please let me know so I can assist you accurately!
