Step-by-step explanation:
is isosceles and 
and 
are base angles.
Isosceles Triangle:
A triangle with two equal sides, and two congruent base angles that means the angles are equal
By the definition, the base angles are equal i.e, 
Since, YZ bisects 
Angle Bisector theorem: An angle bisector is a line or ray that divides an angle into two equal angles
then, 
or
Substitute the value of

Answer:
163
Step-by-step explanation:
Given the following :
Number of visitors on Friday = 3,260
Number increased by 15% on Saturday
Projected percentage increase on Saturday = 20%
Actual percentage increase in number of visitors = 15%
Number of visitors on Saturday :
(100 + 15)% × 3260
115% * 3260
(115/100) * 3260
= 3749 visitors
Projected percentage increase = 20%
Projected number:
((100 + 20)% * 3260
120% * 3260
(120/100) * 3260
= 3912
Difference : (3912 - 3749) = 163
