出门在外也不愁数学题~求解答,要有过程①如下左图,C,D是半圆O上两点, CD/AB=5/11,求cos∠CEB和tan∠CEB②如下右图,若AC,BD的延长线交于点E,CD/AB=5/11,求cos∠CEB和tan∠CEB
（1）连BC∵AB为直径∴角ACB=90度观察弧AD和BC对应的四个角……证三角形ABE和DCE相似得CE/BE=5/11,即cos∠CEB=5/11,tan∠CEB=（4倍根号6）/5&（2）连BD,CE同上有角cdb=ceb=90度角edb=ecb,角dec=dbc&∵直角gdb中,角gde=90-角edb&&& 三角形ECB 中,角ebc=90-角ecb∴角gde=角ebc同理角ged=角dcb证三角形GDE相似于GBC得GD/GB=5/11,即cos∠G=5/11,tan∠G=（4倍根号6）/5&点的标签于题目没对上,你对着图看看吧,不清楚的可以再问题目主要考的圆周角,多观察

x（x+1）竖看第四列3*5
7*13。如果我的回答对你有帮助
17-13=466-45=21
21-17=491-66=25
第五列的答案是二三列的乘积：如3x4=12。4x5=20。5x6=30。6x7=42。7x8=56
第四列的答案是上一拍的前两个数的和与下一列的第一个数的积。如（2+3）x3=15
(3+4)x4=28
(4+5)x5=45
(5+6)x6=66依次推，最后一排的答案是（6+7）x7=91仅供参考。
15+13=2828+17=4545+21=6666+25=91
