Answer:
x=16
Step-by-step explanation:
If the triangles are similar then their sides are in proportion.
Set the proportions 20/(3x+8)=(x-1)/(x-1+27)
solve for x,
cross multiply
20(x+26)=(x-1)(3x+8),
distribute
20x+520= 3x² +8x-3x-8,
combine like terms
3x²-15x-528=0
solve using quadratic formula
x=16 and x= -11 reject because we cannot have negative measurements

Answer:
51°
Step-by-step explanation:
Note that the square in the angle place = 90°.
Also note, that a complete circle is 360°.
Set the equation. Let the ? be denoted by the variable x:
x + 90+ 124 + 95 = 360
Simplify. Combine like terms:
x + (90 + 124 + 95) = 360
x + (309) = 360
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 309 from both sides of the equation:
x + 309 (-309) = 360 (-309)
x = 360 - 309
x = 51
51° is your answer.

$346/100=$3.46 =1% of $346. So, giving 10% discount we $3.46*90=$311.40
Again, $311.40/100=$3.114, providing, 10% discount we get $3.114*90=$280.26.
The net cost after the series discount is $280.26
By the fundamental theorem of calculus,
and so F'(1) = cos(1).
