Answer:
150° and 210°
Step-by-step explanation:
1) to drow a circle with radius=1 in the system of coordinates like in the attached picture;
2) to mark point (-√3/2)≈-0.866 on X-axis (in the picture it is the point M);
3) to graph line AB through point M, the line AB || Y-axis and the points A and B are on the circle with radius=1;
4) to measure the angles ∠ROA and ∠ROB (the points are marked with red colour);
5) finally, m(∠ROA)=150°; m(∠ROB)=210°.
In the picture with the triangles Phillip is correct because the triangle does not give the measurements of the same side so there is no proof of any sides to be the same. With the other picture what I did was I reversed the translation which got the points A (-2,1) B (-5,3) Then I reversed the rotation which got me A(2,-1) and B (5,-3). So line AB endpoints would be located A (2,-1) and B (5,-3).
Hope this helps!
Answer:
x = -6, 6
Step-by-step explanation:
Isolate the variable, x. Find factors of all terms on the left:
x² + 36 = 0
x 6
x 6
(x + 6)(x + 6) = 0
Solve for x:
(x + 6) = 0
x + 6 = 0
x + 6 (-6) = 0 (-6)
x = -6
x² + 36 = 0
x -6
x -6
(x - 6)(x - 6) = 0
Solve for x:
x - 6 = 0
x - 6 (+6) = 0 (+6)
x = 6
x = -6 , 6.
