Answer:
a = 11.71 ; b = 15.56
Step-by-step explanation:
For this problem, we need two things. The law of sines, and the sum of the interior angles of a triangle.
The law of sines is simply:
sin(A)/a = sin(B)/b = sin(C)/c
And the sum of interior angles of a triangle is 180.
45 + 110 + <C = 180
<C = 25
We can find the sides by simply applying the law of sines.
length b
7/sin(25) = b/sin(110)
b = 7sin(110)/sin(25)
b = 15.56
length a
7/sin(25) = a/sin(45)
a = 7sin(45)/sin(25)
a = 11.71
I guess you are asking what is the shape of the cross section.
It will be an ellipse.
Answer:
x≥72
Step-by-step explanation:
Put into an equation then solve.
x/8≥9
x8 x8
x≥72
Hope that helped!
440(100-p)/100=154
440(100-p)=15400
44000-440p=15400
-440p=-28600
p=65%
So the price was discounted 65% off the original price.
