3 pieces times 20 degrees equals 60 degrees <span />
Answer
-41
Step-by-step explanation:
When X =0 Y=-41
First column you are adding 9
-27+9=-18
-18+9=-9
-9+9=0
Second column you are adding 19
-98+19=-79.
-79+19=-60
-60+19/-41
So when X=0 Y=-41
Answer:x=90° y=58° z=32°
Step-by-step explanation:
x=90
y=180-(90+32) sum of angles in a triangle is 180
y=58
y+90+z=180 they are supplementary
58+90+z=180
148+z=180
z=180-148
z=32
As 27 will always be equal to 27, you can place whatever you want for x and y and the equation would still be satisfied, as it turns out that it doesn't depend on the x or y value.
Therefore, the system has infinite solutions.
