32 A?
Hard to say. Is D above or below AC?
IDK
helpppppppppppppppppppppppp
Step 1: Start by identifying the given angles in the problem. We are given that angle BAC is 72 degrees and angle BCD is 113 degrees.
Step 2: Remember that the sum of the interior angles in a triangle is always 180 degrees. So, we can use this information to find angle ABC.
Step 3: To find angle ABC, subtract the given angles from 180 degrees. So, angle ABC = 180 degrees - angle BAC - angle BCD.
Step 4: Substitute the given values into the equation to find angle ABC. angle ABC = 180 degrees - 72 degrees - 113 degrees.
Step 5: Simplify the equation by performing the subtraction. angle ABC = 180 degrees - 185 degrees.
Step 6: Subtract 185 degrees from 180 degrees. angle ABC = -5 degrees.
Step 7: Now, we know that the sum of the interior angles of a triangle is always equal to 180 degrees. Therefore, angle ABC cannot be negative.
Step 8: Since angle ABC cannot be negative, there must be an error in the given information or the construction of the triangle.
Step 9: We cannot determine the measure of angle B without accurate information. So, the measure of angle B remains unknown in this case.
Sorry, I couldn't give a more specific answer! But hey, at least we have a new kind of mysterious triangle!
To find the measure of angle B in triangle ABC, follow these steps:
1. Recall that the angles in a triangle add up to 180 degrees. So, we have:
Angle BAC + Angle ABC + Angle BCA = 180 degrees
2. Substitute the given values:
72 degrees + Angle ABC + 113 degrees = 180 degrees
3. Combine like terms:
Angle ABC + 185 degrees = 180 degrees
4. Subtract 185 degrees from both sides to isolate Angle ABC:
Angle ABC = 180 degrees - 185 degrees
5. Simplify:
Angle ABC = -5 degrees
6. The measure of an angle cannot be negative, so the solution -5 degrees is not valid.
Therefore, we cannot determine the measure of angle B without additional information.
