Answer:
D
Step-by-step explanation:
bc it starts with -square root of 20 and then - square root of 6 and the 3.14 and then square root of 8 and then square root of 18
Consider the triangle (<em>in </em><em>which </em><em>angle</em><em>4</em><em> </em><em>is </em><em>present</em>)
by angle sum property,
20 + 40 + angle4 = 180
60 + angle4 = 180
angle4 = 180 - 60
angle4 = 120
Also,
angle2 = 120 (vertically opposite angles)
angle1 + angle2 = 180 (linear pair)
angle1 + 120 = 180
angle1 = 180 - 120
angle1 = 60
X+ 4? idk I don't really understand the question...
When x is -1 Y will equal -1
