Answer:
10
Step-by-step explanation:
(x + 2) + (-2 + x) = 20
2x + 0 = 20
2x = 20
x = 20/2
x = 10
If this an angle on a straight line the answer is k=73°
Answer:
x = 6
Step-by-step explanation:
the tangent- tangent angle UVW is half the difference of the intercepted arcs, that is
∠ UVW =
(UW - WU ) , then
5x + 17 =
(37x + 5 - (23x - 5) ) ← multiply both sides by 2
10x + 34 = 37x + 5 - 23x + 5
10x + 34 = 14x + 10 ( subtract 14x from both sides )
- 4x + 34 = 10 ( subtract 34 from both sides )
- 4x = - 24 ( divide both sides by - 4 )
x = 6
Answer:
True.
Step-by-step explanation:
I don't know the explanation behind any of it, but a negative number, when multiples by another negative number, is always positive.
