this triangle has 4 angles, angle 1, 129 degress, angle 2, A degress, angle 3, B degress, angle 4, 90 degress. figure out the angle for a and b

1 answer

To find the values of angles A and B, we can use the fact that the sum of the angles in a triangle is always 180 degrees.

Given:
Angle 1 = 129 degrees
Angle 2 = A degrees
Angle 3 = B degrees
Angle 4 = 90 degrees

We know that the sum of all four angles in the triangle is 180 degrees:

Angle 1 + Angle 2 + Angle 3 + Angle 4 = 180

129 + A + B + 90 = 180

Simplifying the equation, we have:

A + B + 219 = 180

Subtracting 219 from both sides:

A + B = -39

Therefore, we cannot determine the values of angles A and B with the given information.
