It is proved in the answer that an exterior angle of the triangle equals the sum of two opposite interior angles.
<h3>
What is the exterior angle property of a triangle?</h3>
If a triangle's side is created, the outside angle that results is equal to the product of the two opposite internal angles.
In the figure given below we can see:
∠BCD is the exterior angle of the triangle
∠ABC + ∠BAC + ∠BCA = 180° (Angle sum property of a triangle)
∠BCA + ∠BCD = 180°(Linear pair)
From both equations we can say that:
∠ABC + ∠BAC + ∠BCA = ∠BCA + ∠BCD
∠ABC + ∠BAC = ∠BCD
Hence Proved

Answer:4
Step-by-step explanation:
Answer:1.3 or 4/3
Step-by-step explanation: 1 to the fifth power is 1 so 1 times 3 is 3. Then 19 - 15 is 4. So you have 4/3 which can stay as 4/3 or you can divide 4 by 3 and get 1.3
