Answer:415
Step-by-step explanation:
Angle DBE + Angle CBE = 90°
(0.1x-22)° + (0.3x-54)° = 90°
(0.4x - 76)° = 90°
(0.4x)° = 166°
x= 1660/4 = 415
(0.1 415 - 22)° + (0.3 415-54)° = 90°
41.5 - 22 + 124.5 - 54 = 90
166 - 76 = 90
I believe its 2. 4*2=8. 2*7=14. 2*10=20
Answer:88.5ft
Step-by-step explanation:
a. What conjecture is being made?
The Conjecture being made is that is it is possible to measure the larger angle of the second fence based on the smaller angle.
b. What key details are given?
That the lines are parallel and the smaller angle is 35 degrees.
c. What is your plan of action?
My plan is to multiply 35 and 2 then subtract 35 times 2 with 360 and the answer is 290 and divide 290 by 2 to get 145 degrees as the larger angle.
Polynomial 1 : x²-x²+4x -2+1 = 4x -1
Polynomial 2 : 3x-x-2x²-2+1 = -2x²+2x-1
Polynomial 3 : 4 -2x+x-x²+x²-x² = -x²-x+4
According to the question,
Polynomial 1+Polynomial2+Polynomial3 + Polynomial4 = 6x
=> 4x -1+ (-2x²+2x-1) +(-x²-x+4) + Polynomial4= 6x
=> -3x²-x+2+Polynomial4= 0
<h2>=> 3x²+x -2= Polynomial4</h2>
