Answer:
x = 44°
Step-by-step explanation:
Since this is an isosceles triangle, the other angle that isn't defined is also 68°. So, since all the angles add up to 180°,
x + 68(2) = 180
x + 136 = 180
x = 44°
Answer:
2,29
Step-by-step explanation:
17,56 = 29,01 - 5x
5x = 29,01 - 17,56
5x = 11,45|:5
x = 2,29
Answer:
32
Step-by-step explanation:
Substitute x = 6 into f(x), that is
f(6) = 6² - 4 = 36 - 4 = 32
Well one dm= 10 cm
12-10= 2 cm
