Answer:
= 52°
Step-by-step explanation:
The obtuse angle at O is twice the angle made at the circumference /by the same segment b.
=52×2=104°
The base angles that are made by isosceles triangle that has the apex with angle 104° equal to (180-104)/2=38°
The radii of a circle are equal and meet tangents at right angles.
Angle a= 90-38= 52°
Answer: The answer is (c) 3 - 4i.
Step-by-step explanation: We are given a point located on the complex plane and we are to select the correct complex number that is represented by this point.
We can see that the co-ordinates of the point on the plane are (3, -4).
Since the point (a, b) can be written in the form a + bi, where 'a' is the measurement along X-axis and 'b' is the measurement along Y-axis, so the point (3, -4) an be written in the following form:
(3, -4) = 3 + (-4)i = 3-4i.
Thus, (c) is the correct option.
