Mathematics
1 answer:
DanielleElmas [232]3 years ago
4 0

Answer:

  • If angle C is 90 degrees (def. of right angle) then the sum of angle A and B has to 90 degrees since angle A + B + C (90°) = 180°

Statements and Reasons:

3. Angle C is 90 degrees because of the definition of right angle.

4. Angle A + angle B + angle C is 180 degrees because of triangle sum.

5. Angle A + angle B + 90 = 180 because of substitution postulate.

6. Angle A + angle B is 90 degrees because of subtraction postulate. (subtract 90 from both sides from the equation above this step).

7. Angle A and angle B are complementary.

What is the distance from X to Y?
Rama09 [41]

Answer:

Step-by-step explanation:

To find the distance between two points, (A, B) and (C, D), you can use the following distance formula:

distance = \sqrt{(A - C)^{2} + (B - D)^{2}}

Plugging in the points from the problem, you'll get the following:

\sqrt{(0 - 9)^{2} + (6 - (-6))^{2}}

\sqrt{(-9)^{2} + (12)^{2}}

\sqrt{81 + 144}

\sqrt{225}
