What are the main elements in a measurement system and what are their functions. Which elements are not needed in some measurement systems and why are they notneeded?

where are the images of the functions i can only see the question you typed.

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

umm im not really sure because i never had to do this

step-by-step explanation:

oh

nu stiu chiar nu stiu sa o fac
