The correct answer is D (3x - 4y = 4)

Explanation:

Let (x1, y1) be (0, -1) and (x2, y2) be (-4, -4).

y - y1 = (y2 - y1)/(x2 - x1) * (x - x1)
y + 1 = (- 4 + 1)/(- 4 - 0) * (x - 0)
y + 1 = (-3)/(-4) * x
y + 1 = (3/4)x
(y + 1) * 4 = 3x
4y + 4 = 3x
4 = 3x - 4y
3x - 4y = 4

Find the measures of EAF DAE and CAD
sdas [7]
You have to build an equation to find the answer,

angles in a straight line add upto 180° 
so your equation would be,

12x+30°=180°
      -30    -30
=12x=150°
   ÷12  ÷12
=x=12.5°

now find the measures of the angles by using 12.5 as x.

angle EAF= 2x
                 =2×12.5
                 =25° degrees

angle DAE= 4x
                 =4×12.5
                 =50°degrees

angle CAD=6x
                 =6×12.5
                 =75°degrees

check,
30+25+50+75=180°degrees

hope this helps.......

Find the area of the figure below<br><br> A.288.62<br> B.266.22<br> C.186.66<br> D.236.6
Archy [21]

Answer:

A. 288.62

Step-by-step explanation:

Area of two triangles = 15.3 * 10.4 = 159.12

Area rectangle = hypotenuse triangle * 7

hypotenuse = √108.16 + 234.09

Hypotenuse = 18.5

Area rectangle = 18.5 * 7 = 129.5

129.5 + 159.12 = 288.62

Answer = A. 288.62

If my answer is incorrect, pls correct me!
