Complementary angles are 2 angles that add up to 90°
Since you don’t have any of the values of either angles, just divide 90 by 2 to get 45. Each angle is 45°

Step-by-step explanation:

complementary angles sum up to 90

x + y = 90

45 + 45 = 90

x = 45 \\ y = 45

Help plzzzzzzz <3333
STatiana [176]

Answer:

It is $66.50 cheaper to purchase a return trip ticket than it is to purchase 2 one-way tickets.

Step-by-step explanation:

It is asking us how much does 2 one-way tickets costs as opposed to a return trip ticket.  First, let's figure out how much does 2 one-way tickets cost.

Equation:

287.75 x 2 = 575.50

2 one-way tickets cost $575.50.

Then, to find the difference, subtract the return trip cost from the two one-way tickets.  

Equation: 575.50 - 509.00 = 66.50

The difference between the two is $66.5

Conclusion: It is $66.50 cheaper to purchase a return trip ticket than it is to purchase 2 one-way tickets.

I hope this helps!

Given congruent triangles name the corresponding sides and corresponding angles
Alborosie

Answer:

See explanation

Step-by-step explanation:

Given \triangle ABC\cong \triangle ADC

According to the order of the vertices,

  • side AB in triangle ABC (the first and the second vertices) is congruent to side AD in triangle ADC (the first and the second vertices);
  • side BC in triangle ABC (the second and the third vertices) is congruent to side DC in triangle ADC (the second and the third vertices);
  • side AC in triangle ABC (the first and the third vertices) is congruent to side AC in triangle ADC (the first and the third vertices);
  • angle BAC in triangle ABC is congruent to angle DAC in triangle ADC (the first vertex in each triangle is in the middle when naming the angles);
  • angle ABC in triangle ABC is congruent to angle ADC in triangle ADC (the second vertex in each triangle is in the middle when naming the angles);
  • angle BCA in triangle ABC is congruent to angle DCA in triangle ADC (the third vertex in each triangle is in the middle when naming the angles);
