Answer:
=204.13 inches.
Step-by-step explanation:
Using the side x, we can use sine to find the hypotenuse of the triangle with the angle marked 30°.
Sin 30 =x/hypotenuse.
sin 30 = 27/hyp
hyp= 27/sin 30
=54 inches
We can also find the adjacent as follows.
Cos 30 = adjacent/ 54
Adjacent= 54 cos 30
=46.77 inches
Using the angles marked 45 we can find the hypotenuse of the isosceles triangle.
sin 45= x/hypotenuse
sin 45 =27/hypotenuse
hypotenuse = 27/sin 45
=38.18 inches
The hypotenuse of both the triangles making the isosceles triangle are 38.18 inches long.
Perimeter = 54+ 46.77+27+ 38.18+38.18
=204.13 inches.

Answer:
The answer is b:153
Step-by-step explanation:
Supplementary angle are angles whose angles add up to 180 degrees.
So percent means parts out of 100
so 12%=12/100=1.2/10=0.12/1=0.12
3.84 is 12% of what
'of' means multiply
'is' means = sign
therefor
3.84=0.12 times what
divide both sides by 0.12
32=what
th enumber is 32
Slope is y2 - y1/ x2-x1 so # 1 would be 7-0/6-0 or 7/6
