2x=34
x=17
3(17)-11 17+23
=40 =40
explanation ;
you would equal them because they are congruent . & you substitute x for 17 in each equation to find out the degrees of both of the angles :)

Answer:63
Step-by-step explanation:
Answer:
∠ GDH = 67.5°
Step-by-step explanation:
The measure of the chord- chord angle GDH is half the sum of the measures of the arcs intercepted by the angle and its vertical angle.
∠ GDH = 
(GH + EF) = (90 + 45)° = 0.5 × 135° = 67.5°
Because to find the perimeter of a shape you have to add all the sides together so you would take 26.46 and divide it by 4 (since squares have 4 sides) to get 6.165
