Determine an equation of the line that passes through the point (-2, 3) and is perpendicular to the line whose equation is−2x+y−2 =0. Then draw both lines on the same pair of axes.

Since the line passes through  (−2,3)  we can plug it in the equation to find out the value of  C  

2(−2)−3−2+C=0⟹C=9  

So the equation is

2x−y−2+9=0  

or

2x−y+7=0

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
