Answer:
none
Step-by-step explanation:
i do not thinn it is any of these as 180 -120 =60 so uvt is 60 and t is 50. every triangles angles add up to 180 so 50 +60 = 110 and 180 -110 is 70. so i think the answer is 70 degrees and if i am wrong please correct me and explain how.
150 units squared
Consider
Substitute t= sinx
then dt = cos x dx
Hence,
that depends what is the question
I'd have to say it's A. Please don't blame me if I'm wrong. :)
