Answer:
x =20
Step-by-step explanation:
We can use similar triangles and proportions to solve. Take the smaller triangle side on top and the larger triangle side on the bottom.
11 10
---------- = --------------
11+121 10 +5x+10
Combine like terms
11 10
---------- = --------------
132 5x+20
Using cross products
11*(5x+20) = 10*132
55x+220 = 1320
Subtract 220 from each side
55x+220-220 = 1320-220
55x = 1100
Divide by 55
55x/55= 1100/55
x =20
Answer
Step 1: Add -x^2 to both sides.
x2+c+8x+−x2=0+−x2
c+8x=−x2
Step 2: Add -8x to both sides.
c+8x+−8x=−x2+−8x
c=−x2−8x
Answer:
c=−x2−8x
I hope is is the answer you are looking for
It will be secx = 2
or, cosx = 1/2
or x = Π/3 , 5Π/3
To have all positive terms I think
