PLEASE MARK ME THE BRAINLIEST.
sin 75 =√2+√6/4
Step-by-step explanation:
Sin(75)=sin(30+45)
On comparing,sin(45+30)=sin(a+b)
Putting values,
Sin(45+30)=sin45*cos30+cos45*sin30
-> 1/√2*√3/2+ 1/√2*1/2
-> √3/2√2 + 1/2√2
-> √3 +1 / 2√2
-> √3 +1/2√2 *√2/√2 (rationalising denominator)
-> √6+√2/4
Answer:
The washback effect' of frequent changes in question paper design and blueprint at the secondary and senior-secondary level has muddled up the question papers of the middle level classes so much so that different schools often use different question paper patterns with a variety of question types and weight of marks. These changes are so rapid and at times so tentative that it is really very difficult for a book like this to provide custom-made question papers for every school. Nonetheless, we have prepared 6 different types of question papers in Module 8 which individual schools can use as models for their question papers. Notwithstanding the differences in question paper styles, question types and weight of marks, a typical question paper of English usually should have the following 4 sections: Reading Writing, Grammar and Literature that together account for 70–90 marks. Such a question paper presupposes that the listening and speaking skills will be assessed separately, either during a term or at the end of it. Reading Jution. The reading section of the paper contains unseen comprehension passages which can be literary, discursive or factual. These passages generally include a variety of questions like multiple choice questions (MCQs), true-false, cloze or gap-filling, sentence completion, table completion, objective type, very- short-answer type questions and word-attack or vocabulary based questions. Some questions may test students' ability to interpret, infer ideas and information and in some students may have to analyze how one part of the text is related to another. Number of passages in question paper as well as the number and type of questions on each passage may vary, but the norm is 2 to 4 passages for 15 to 25 marks if the question paper is of 70–90 marks. Usually two to four different types of question types are used to test global and local comprehension. The total length of all the passages put together may be 600 to 1100 words, although individual passages may have varying lengths. The thumb rule should be that the complete reading section should be doable in about 40 minutes if the paper is of 3 hours.
