Find the length of BC.

Question 2. In the diagram below, m∠VCR=126˚.
Find the measure of ∠NCF.

question 2: x=55

Step-by-step explanation:

I left an image below to show you my work. I hope this helps!

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
