Answer:
Step-by-step explanation:
we know that the triangle to the center is an isosceles, so the two angle on the circle of that triangle are the same. both 41, so 41*2 =82
all the way around that isosceles triangle is 180 so
180-82 = 98
the angle at O is 98°
the arc BC spans 98°
angle 'a' is 1/2(98°)
a = 49°
Mathematical Induction is used in proving the statement is which holds the element in processing another statement and also proves that it is the key to proceed to another statement. In geometry, it is used to proved that the present geometric pattern hold the element in continuing in predicting the next geometrical pattern and also the next pattern also has this element.
why is no one answering? I also need help in this question!!!!
