Answer:
Step-by-step explanation:
When given points, whether that be on a graph or a table, those can be used to find the slope using the equation y2 - y1 / x2 - x1.
y2 - y1 / x2 - x1
(Pick 2 pairs if points. In this case I am using (2, -1) and (-1, 3) from your data table. From here, just plug it in.
-1 - 3 / 2 + 1
-4 / 3
Your slope is -4/3. Hope that helps! Take care.

Answer:
155.45 cm
Step-by-step explanation:
Given: Length of side x (opposite)= 89.75 cm
Angle is 30°
Lets use tangent rule to find the value of y (adjacent).
∴
Using trigonometry table
⇒
Now, cross multiplying both side
⇒ y=
∴ 155.45 cm is the length of side y.
