Since angles A and B are complementary, their measures add up to 90°. In other words, we have the equation:
X + 2X = 90°.
Combining like terms, we get:
3X = 90°.
Dividing both sides by 3, we find:
X = 30°.
Therefore, the measure of angle B is:
2X = 2 * 30° = 60°.
In a geometric diagram angle, an and angle B are complementary and they form a straight line with angle. See if an angle A equals X and MIn a geometric diagram angle a and angle B are complementary and they form a straight line with angle C if an angle a equals X and an angle B equals 2X and an angle C equals 90° what is the measure of angle B
