Answer:
125° and 55°
Step-by-step explanation:
∠ BCE and ∠ ECF are adjacent angles and are supplementary, thus
10x + 15 + 5x = 180, that is
15x + 15 = 180 ( subtract 15 from both sides )
15x = 165 ( divide both sides by 15 )
x = 11
Thus
∠ BCE = 10x + 15 = 10(11) + 15 = 110 + 15 = 125°
∠ ECF = 5x = 5(11) = 55°
Answer:
y>4x-2
Step-by-step explanation:
First let us find the equation of the line.
Given points (1,2) and (0, -2), the slope would be
(2-(-2))/(1-0) = 4/1= 4
The intercept is at -2, so the full equation would be
y=4x-2
However, we need to find the inequality of the graph. Everything greater than our line/above our line is included. Also notice that the line is dotted, which means that the line itself is not included.
Our equations should be,
y>4x-2
