Answer:   544 cm²

<u>Step-by-step explanation:</u>

There are 5 sections to the tent:

  1. Front (triangle):  A = \frac{1}{2} · b · h
  2. Back (triangle): same dimensions as Front
  3. Base (rectangle): A = L · w
  4. Left Side (Rectangle): A = L · w
  5. Right side (rectangle): same dimensions as Left Side

Total Surface Area = Front & Back  +   Base  +  Sides

                                =  2[\frac{1}{2}(12 · 8)]     +  (12 · 14) + 2(14 · 10)

                                =        96            +     168    +  280

                                =  544

Secant AD and AE intersect in the exterior of a circle. ∠ BAC measures 27.42° and the measure of DE is 73.18°. Determine the mea
sveta [45]

Answer:

BC = 18.34°

Step-by-step explanation:

The secant- secant angle BAC is half the difference of the intercepted arcs, that is

\frac{1}{2} ( DE - BC) = 27.42

\frac{1}{2} ( 73.18 - BC ) = 27.42 ( multiply both sides by 2 )

73.18 - BC = 54.84 ( subtract 73.18 from both sides )

- BC = - 18.34° ( multiply both sides by - 1 )

BC = 18.34°

What is the equation standard form of through (2,-4))and the slope is -4
Sloan [31]

Answer:

4x + y = 4

Step-by-step explanation:

Equation of Line in point slope form is given as:

y - y_1= m(x-x_1)

Plug x_1= 2\: and\: y_1= - 4 in the above equation we find:

y - ( - 4) =  - 4(x - 2) \\  \\ y + 4 =  - 4x + 8 \\  \\ 4x + y + 4 - 8 = 0 \\  \\ 4x + y - 4 = 0 \\ \\ 4x + y = 4 \\this \: is \: the \: required \: equation.
