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.

WebApr 6, 2024 · Adding tanC on both sides we get: ⇒ tan A + tan B + tan C = tan C + tan C As we know, tan A + tan B + tan C = 6 so we get: 6 = 2 tan C. Dividing both sides by 2, we get tan C = 3. Also we get: tan A + tan B = 3. Now we have tan A + tan B = 3 and tan A tan B = 2. So values of tanA and tanB should be 2 and 1.
