Answer:
55°
Step-by-step explanation:
180°-70°=110° (sum of angles on a straight line gives 180°
The size of each of the four remaining angles=110°/4 = 27.5°
<X + <Y = 27.5° + 27.5°=55°
Answer:

Step-by-step explanation:
In the equation
, 'k' is the only common term.
Factor out 'k':

Hope this helps.
The output will be -2.
Output, generally, refers to the 'y' coordinate when the input is 'x'.
The answer is 2/-2
Using the formula y^2-y^1/x^2-x^1
5 - (x + 5) - (2x + 4)
5 - x - 5 - 2x - 4
-3x - 4
