Answer:
Step-by-step explanation:
If two vertices of your triangle touch the circle and the third angle (a right angle located at the center) then x + y + 90 degrees = 180 degrees, or
x + y = 90 degrees.
Answer:
When we rotate a point A(1, 4) 180 degrees counterclockwise about the origin, the coordinates of point A(1, 4) transformed to A'(-1, -4).
Step-by-step explanation:
We know that 180 Degree Rotation.
We know that when we rotate a point, let say P(x, y), 180 degrees counterclockwise about the origin, the coordinates of point P(x, y) transformed to P'(-x, -y).
In other words, the sign of both x and y coordinates are reversed.
Thus, the rule is:
P(x, y) → P'(-x, -y)
Given the point (1, 4)
P(x, y) → P'(-x, -y)
A(1, 4) → A'(-1, -4)
Thus, when we rotate a point A(1, 4) 180 degrees counterclockwise about the origin, the coordinates of point A(1, 4) transformed to A'(-1, -4).
It isn't. For example, if I integrate the function [ 2sin(θ) + 3cos(θ) ] between
the limits of -π and +π, my age does not appear anywhere in the result.
It depends on how the calculation is set up, and what steps you go through
to get the result. You haven't told us anything about that.
Acute angles is the answer
