2ways you can solve that is by multiplying 9 by 1 then by 5 or 9by 5 then by 1
We know that a triangle adds up to 180 degrees.
Here, 130 is a vertical angle so on the opposite side the triangle makes, it is also 130. Then we could add 130 to 25
130 + 25 = 155
Now let’s subtract this from 180.
180 - 155 = 25.
X is a supplementary angle to 25 so subtract 25 from 180.
180 - 25 = 155
X = 155.
Answer:
+3 and -4
Step-by-step explanation:
as
+3×-4=-12
and
-4+3=-1
Direct variation is when one variable changes the other changes in proportion of the first, therefore all the above
52 is the answer I believe
