Answer:
I would say that it is none of the above that one is much more reasonable than the other ones
Step-by-step explanation:
Angles in a triangle must add up to 180, so the missing angle inside the triangle is 180 - (70 + 40), which is 70.
Angles on a straight line (i.e. the line BD) must add up to 180, and because we know part of that angle is 70, x must be 180 - 70, which is 110.
Hence, x is 110 degrees.
52mph, depending what unit you need the answer in you may have to use conversions
What are you suppose to find i feel like it doesn't really say
