Web1·三角形ABC不是等边三角形,其外接圆半径为2,最长边BC=2倍根号3,求sinB+sinC的取值范围.2·三角形ABC中已知tanA=2分之1,tanB=三分之一,最长边为1,（1）求角C的大小（2）求三角形ABC的最短边的长. WebMar 30, 2024 · Best answer Correct Answer is (C) 3π 4 3 π 4 Since we know that tan-1 x + tan-1 y = tan−1( x+y 1−xy) t a n − 1 ( x + y 1 − x y) ⇒ tan-1 2 + tan-1 3= tan-1( 2+3 1−(2×3)) ( 2 + 3 1 − ( 2 × 3)) = tan-1( 5 −5) ( 5 − 5) = tan-1(-1) Since the principle value of tan lies in the range [0, π] ⇒ tan-1(-1) = 3π 4 3 π 4 ← Prev Question Next Question →

WebThe correct option is B. We have tan A = - 1 2 and tan B = - 1 3. Now, tan(A + B) = t a n A + t a n B 1 − t a n A t a n B = − 1 2 − 1 3 1 − 1 2. 1 3 = -1. ⇒ tan(A + B) = tan 3 π 4. Hence, A + B = 3 π 4. Web三角形ABC中,tanA=1/4,tanB=3/5,AB=根号17,求BC的边长. 角C我求出来是135度. 这有用么. 恩.我按你的算出来根号2啊. mapc winter council https://edwoodstudio.com
