Find the length of each line segment, PLEASE HELP

Step-by-step explanation:

the graphic shows us - the 2 end points are :

(-4, -4) and (4, -1)

the distance between these 2 points (= length of the line segment) is calculated via Pythagoras for right-angled triangles.

c² = a² + b²

c is the Hypotenuse and the distance between the 2 points. a and b are the legs of the triangle enclosing the 90 degree angle, as they are the differences between the x and the y coordinates of the points.

so,

distance² = (-4 - 4)² + (-4 - -1)² = (-8)² + (-3)² = 64 + 9 = 73

distance = sqrt(73) = length of line segment.

found it xd it ok yt

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
