Step-by-step explanation:
Answer:
x = 35, x = 27
Step-by-step explanation:
(9)
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
141° is an exterior angle, thus
x + 24 + 2x + 12 = 141 , that is
3x + 36 = 141 ( subtract 36 from both sides )
3x = 105 ( divide both sides by 3 )
x = 35
-----------------------------------------------------------
(11)
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
2x - 9 + 3x + 2x = 180
7x - 9 = 180 ( add 9 to both sides )
7x = 189 ( divide both sides by 7 )
x = 27
Answer:
f(10) means to input x = 10 into the function.
From inspection of the given function:
![\sf f(10)=\dfrac{10}{2}=5](https://tex.z-dn.net/?f=%5Csf%20f%2810%29%3D%5Cdfrac%7B10%7D%7B2%7D%3D5)
the "10" is the numerator of the fraction.
Therefore, swap the "10" for "x" to give the function in terms of x:
![\sf f(x)=\dfrac{x}{2}](https://tex.z-dn.net/?f=%5Csf%20f%28x%29%3D%5Cdfrac%7Bx%7D%7B2%7D)
