I need #1 please help!!

We are given that ∠E and ∠B are right angles and C is the midpoint of AD.

Angle BCA is congruent to Angle DCE (Vertical Angles are Congruent) and Triangle ABC is congruent to DEC (SAS (side-angle-side)).Vertical angles are angles across from each other when two lines intersect. Vertical angles are always congruent. ACB and DEC are a pair of vertical angles, and BCD and ACE are a pair of vertical angles.Side-Angle-Side (SAS) is a congruence shortcut for triangles. When two pairs of congruent sides an one pair of congruent angles (between the sides) are in two triangles, we can assume the triangles are congruent.

Do the math. she originally had 50 dollars on her gift card and she had 12 dollars left on her gift card after she finished her shopping spree. if you subtract 50 minus 12 you get thirty eight dollars as your answer. so therefore, ciara spent 38 dollars total o
