1.When all the three cut outs of the angles A, B, C placed adjacent to each other at a point, then it forms a line forming a straight angle, i.e. 180°.
Flence, it is proved that the sum of the three angles of a triangle is 180°.
Therefore, ∠A + ∠B + ∠C =180
Answer:
D. (3, -1).
Step-by-step explanation:
The vertex for ( x - a)^2 + b is (a, b).
Comparing (x - 3)^2 - 1 with this we get:
a = 3 and b = -1.
