Answer:

x=16.782

Step-by-step explanation:

a=40*

b=20

c=90*

d=40* (corner in lower right corner, we know it equals 40* because all triangles equal 180*)

e=26.108 (bottom side)

Hope this helps! BH

Answer:

214

Step-by-step explanation:

A circle is 360 degrees

Arc EF is 146 degrees

EF + EDF = full circle

146 + EDF = 360

Subtract 146 from each side

146-146 +EDF = 360-146

EDF =214

Answer:

Step-by-step explanation:

The wording on this is not the best.  It sounds like the 1 zero has even multiplicity (that's because of where the modifier is). On top of that it has an odd power.  You could try this. y =x*(x^2+1)^2

The problem is not with the power. It gives x^5. The problem is with the multiplicity of the one place where it crosses. (X^2 + 1) does factor, but it gives a complex root. I'm not sure that's allowed. However, it is the best I can do.

HELP I NEED THIS WITHIN 2 MINUTES AB if AC = 13.2 And BC = 6.8
AleksandrR [38]

Answer:

AB = 6.4

Step-by-step explanation:

Assuming that AB + BC is AC, then we can say the following:

AB + BC = AC

AB + 6.8 = 13.2

AB + 6.8 + -6.8 = 13.2 + -6.8

AB = 6.4

Cheers.

Part a:-
The base of each triangle is 4 inches long. 
Their  height is 3/2 * 4 = 6 inches.

b 
The combined  area of the triangular faces = 4 * 1/2 * 4 * 6 =  48 sq ins

c
Surface area of the pyramid =  48 + area of base = 48 + 16  = 64 sq ins.
