作BC邊上的高AD??并設(shè)AB為χ

因為AB=AC??所以可得AD⊥BC?且BD=DC??

所以在直角三角形里有?AD=BD2+AB2=(√10/2)2+χ2??????????????????????????????????????????????????????????????????????????????所以ΔABC的面積可表示為

?①?SΔABC=BC×AD=√10×【(√10/2)2+χ2】

?②SΔABC=AB×CH=χ×3/5χ

由①=②可解得CH=3/5AB=3/5χ=3

tanB=AD/BD=3

要擅長設(shè)未知數(shù)和劃輔助線哦!

向左轉(zhuǎn)|向右轉(zhuǎn)

不要扣語法,那樣得不償失,建議你多讀多背,英語是一種本能,不像數(shù)學(xué)題,建議你多去看看李陽老師的演講,看看什么才叫做學(xué)英語,相信你看過后就不會對你所提問題的答案感到關(guān)心了。最好祝你持之以恒,學(xué)好英語。
初中英語冀教版都有哪些人物?
1個回答2024-08-11 20:04

有如下的人物:李雷;韓梅梅;林濤;Jim;Kate;Lily&Lucy ;Tom;Ann。 90后初中英語課本主要是李雷和韓梅梅。 李雷和韓梅梅(Li Lei and Han Meimei)是人民教育出版社20世紀(jì)90年代的初中英語教科書里的兩個主要人物。2001年改版后不再出現(xiàn),此后2009年人民教育出版社出版了小學(xué)英語配套教材《派斯英語》延續(xù)了這個人物設(shè)定。 這套人教版英語教材,1990年開始在北京崇文區(qū)、四川成都等8個縣市區(qū)試用,1993年成為全國(除上海外)通行英語初中教材。 有人估計,從1990年至2000年,10年間使用人教版英語教材的中學(xué)生,高達(dá)上億。2001年以后,人民教育出版社初中英語教科書改版,課文里的“Han Meimei”改為“Han Mei”,只在練習(xí)中余留了少量“Han Meimei”這一稱呼。從此,“李雷和韓梅梅”這一表述暫時告一段落
