-1+(-3) is 3 units from -1 in the left direction
-1+(-3) is blank units from -1 in the blank direction
-4 is 3 units from -1 in the left direction
because we know that
in the real line if we go 3 units in left from -1 we get -4
since in the real number line
the pattern is ................ - 5, -4, -3, -2, -1 ,0,1,2,3,4,5,............
thus we get
-1+(-3) is blank units from -1 in the blank direction
-4 is 3 units from -1 in the left direction

Answer:
pls this question is not complete
Answer:
130°
Step-by-step explanation:
1. Obtain an undistorted picture of the angle. (I enlarged it on my flat computer screen.)
2. Position the protractor so the center mark is on the vertex and the 0° mark is aligned with one ray of the angle.
3. Read the angle measure on the protractor scale, recognizing that the value is more than 90°. (My protractor has two scales, each supplementary to the other.)
__
It is best to use the original of the angle as printed on the original curriculum materials. Any photocopying or printing can distort the angle, giving it a different value that originally intended. (Dilation does not change the angle, but often copiers and cameras have a different scale factor in one direction than in another. That <em>does</em> change the angle's measure.)
