Those are angles who measure add up to 180° the measures are eight equals 67B equals 2X +20 and sequels ask what is the measure of the
missed angle.
To find the measure of the missed angle, we can use the fact that the sum of angles in a triangle is 180°.
Let's start by labeling the three given angles:
Angle 1: 8
Angle 2: 67B
Angle 3: 2X + 20
We know that the sum of these three angles is 180°:
8 + 67B + 2X + 20 = 180
Now let's solve for the missing angle:
67B + 2X + 28 = 180
67B + 2X = 152
Since we don't have any additional information or values for B or X, we cannot determine the exact measure of the missed angle.
