Find the total surface area of these triangular prisms -

Mathematics

yuradex [85]4 years ago

Answer:

1. S = 184cm^2

2. S = 1446 cm^2

Step-by-step explanation:

In order to calculate the surface area you take into account the five faces of a triangular prism. You calculate the area of two rectangle triangle, and three rectangles. This can be summarized in the following formula:

S=\frac{1}{2}hw+\frac{1}{2}hw+hl+sl+wl\\\\S=hw+(h+s+w)l

h: height

w: width

s: slope

l: length

1. By replacing you obtain:

S=(6cm)(4cm)+(6cm+10cm+4cm)(8cm)=184cm^2

2.

S=(18cm)(7cm)+(18cm+30cm+7cm)(24cm)=1446cm^2

joja [24]
You are asked to do this problem by graphing, which would be hard to do over the Internet unless you can do your drawing on paper and share the resulting image by uploading it to Brainly.

If this were homework or a test, you'd get full credit only if you follow the directions given.

If <span>The points(0,2) and (4,-10) lie on the same line, their slope is m = (2+10)/(-4), or   m =-3.  Thus, the equation of this line is y-2 = -3x, or y = -3x + 2.

If </span><span>points (-5,-3) and (2,11) lie on another line, the slope of this line is:

m = 14/7 = 2.  Thus, the equation of the line is y-11 = 2(x-2), or y = 11+2x -4, or y = 2x + 7.

Where do the 2 lines intersect?  Set the 2 equations equal to one another and solve for x:

</span>y = -3x + 2 = y = 2x + 7.  Then 5x = 5, and x=1.

Subst. 1 for x in y = 2x + 7, we get y = 2(1) + 7 = 9.

That results in the point of intersection (2,9).

Doing this problem by graphing, on a calculator, produces a different result:  (-1,5), which matches D.

I'd suggest you find and graph both lines yourself to verify this.  If you want, see whether you can find the mistake in my calculations.

Answer:

c=93

Step-by-step explanation:

35+3(x+2)+52=180

87+3(x+2)=180

87+3x+6=180

93+3x=180

3x=180-93

3x=87

x=87/3

x=29

3(29+2)

3(31)=93
