Answer:
54/6 +54 = 63
Step-by-step explanation:
In trigonometry laws, there's a equation to solve this problem :
sin (a-b) = sin(a) . cos(b) - sin (b) . cos(a),
so by assuming that a = π, b = θ, so the equation will be like this..
sin (π-θ) = sin(π) . cos(θ) - sin (θ) . cos(π),
= 0 . cos(θ) - sin(θ) . (-1)
= sin(θ) = 0.57
Hope this will help you :)
Answer:
Step-by-step explanation:
We know that we are dealing with parallel lines, as there are double headed arrows on each of the lines, pointing in the same direction.
This means we can use corresponding / alternate angle laws.
We know that the angles on a straight line add up to 
, so we can solve for the angle just above the 
to try and see if that will help us.
(Our angle, added to another angle we don't know yet is 180)
Solve for 
We can now apply the corresponding angle law, (as we have an 'F' shape), to determine that:
Answer:
30

Similar figures
63/54 = 35/X
X = 35 × 54/63
X = 30
Answer:
parallel, perpendicular are opposite
