Answer:
Option D is correct.
The measure of 
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:
Perimeter = 78.7 inches
Step-by-step explanation:
From the given question, applying the Pythagoras theorem to one of the congruent triangles formed, we have;
= 
+ 
= 
+ 
=841 + 81
= 922
hyp = 
= 30.3645
The perimeter of the triangle can be determined as;
perimeter = 
+ 
+ 
= 30.3645 + 18 + 30.3645
= 78.729
The perimeter of the triangle = 78.7 inches
