Answer:
C) x = 20.8
Step-by-step explanation:
Since the line with the length equal to 6 forms a right angle on line x then we know it is perpendicular and bisects it.
Plug in the values: a^2 + b^2 = c^2
a^2 + 6^2 = 12^2
a^2 + 36 = 144
a^2 + 36 - 36 = 144 - 36
a^2 = 108
√a^2 = √108
a = √108
a = 10.3923048454
a = 1/2 x
2a = x
2(10.3923048454) = x
x = 20.7846096908
x = 20.8
Step-by-step explanation:
- 90 + (x + 5) + (2x - 2) = 180
- x + 5 + 2x - 2 = 180 - 90
- 3x + 3 = 90
- 3x = 87
- x = 29
Answer:
we need more
Step-by-step explanation:
Answer:
2x² = -8
x² = -4
The answer is no real solutions (x ∉ R) because a perfect square cannot be negative.
