Answer:
x = 21, m∠A = 23°, the measure of angle in the right = 67°
Step-by-step explanation:
The angles of a triangle sum up to 180°.
Right angles equals to 90°.
Thus, (2x - 19)° + (3x + 4)° + 90° = 180°
=> 5x + 75 = 180
=> 5x = 105
=> x = 21
m∠A=> 2(21) -19 = 23°
the measure of angle in the right=> 3(21) + 4 = 67°
Answer:
D. none
Step-by-step explanation:
The point in geometry is defined as the location.
Point A is described as the location of A on any given plane.
Point is represented as a dot.
A dot has no physical dimension like depth, height, thickness or size.
Hence, any two points can not be compared on the basis of any physical parameter.
