(f/g)(x) = (2x² - 8)/(x - 5)
(f/g)(3) = (2(3)² - 8)/(3 - 5)
= (18 - 8)/(-2)
= 10/-2
= -5
The sum of the angles in a triangle is 180°, then:
68°+26°+x°=180°
Solve it as an equation:
68+26+x=180
x=180-68-26
x=86°
I think that it is D or A
Answer:
see explanation
Step-by-step explanation:
In a trapezium the lower base angle is supplementary to the upper bas angle on the same side, thus
4x + 91 - 9x + 59 = 180, that is
- 5x + 150 = 180 ( subtract 150 from both sides )
- 5x = 30 ( divide both sides by - 5 )
x = - 6
Thus
∠ N = - 9x + 59 = - 9(- 6) + 59 = 54 + 59 = 113°
∠ K = 4x + 91 = 4(- 6) + 91 = - 24 + 91 = 67°
