Answer:
1. Angles 2, 3 and angles 1,3 are complementary angles(Given)
2. To prove :
Since Angles 2, 3 and angles 1,3 are complementary.
When angles are complementary, then the sum of the measures of angles is 90 degrees.
So, and (Definition of Complementary angles)
3. (Substitution)
4. (Subtraction property of equality)
Step-by-step explanation:
Answer:
5: 45 miles
6: y=20x
Step-by-step explanation:
Step-by-step explanation:
5x^2 - 20x + 20 = 5x^2 - 20x + 20
5(x^2 - 4x + 4) = 5(x^2 - 4x + 4)
(5 + 5) (x^2 - 4x + 4)
Because the triangle with the legs 2 and 2 would need to have a third leg less than 4 and greater than 0 and a triangle with side lengths 2 and 4 would need a third side of less than 6 and greater than 2
