How to determine if an angle of a triangle is acute or obtuse?
WebWe have to prove that tan A + tan B + tan C = tan A*tan B*tan C for any non-right angle triangle. For any triangle the sum of the angles is equal to 180 degrees. If we take a triangle ABC, A + B ... WebApr 6, 2024 · Hint: In this question, we are given triangle ABC, therefore angles of $\Delta ABC$ are $\angle A,\angle B\text{ and }\angle C$. We are given $\tan A+\tan B+ \tan C=6$ and $\tan A\tan B=2$. We need to find the type of triangle. For this, we need to find ... using values of tanA, tanB, tanC found from the given two conditions. WebIf θ is an acute angle in a right triangle and tan θ = 5 2 , then the length of the leg opposite θ is always 2. Choose the correct answer below. A. The statement is true because tan θ is a ratio of length of the adjacent side to the length of the opposite side of a right triangle. So, the length of the leg opposite θ need not always be 2 . B. The statement is false because … medina county ohio divorce records
