WebWhen A + B + C = 180 ∘ tanA + tanB + tanC = tanAtanBtanC. We know that tan(A + B) = tanA + tanB 1 − tanAtanB and that and that A + B = 180 ∘ − C. Therefore tan(A + B) = − tanC. … WebFor ABC shown above, ∠CAD is the exterior angle for ∠A and ∠B and ∠C are the two remote interior angles. We know that ∠CAB + ∠B + ∠C = 180°. Also, ∠CAB and ∠CAD form a straight angle, so ∠CAB + ∠CAD = 180°. Since both sums equal 180°: ∠CAB + ∠CAD = ∠CAB + ∠B + ∠C ∠CAD = ∠B + ∠C The same can be shown for any exterior angle of any triangle.
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 … WebApr 6, 2024 · Hint: In this question, we are given triangle ABC, therefore angles of $\Delta ABC$ are $\angle A,\angle B\text{ and }\angle C$.
