The line of symmetry is x = 8, and it means that it takes 8 seconds to reach the maximum height and 8 more seconds to reach the ground.
Given:
The measure of an angle is 50 degrees.
To find:
The complement of the given angle.
Solution:
We know that the sum of an angle and its complement is 90 degrees.
Let x be the complement angle of 50 degrees.



Therefore, the measure of complement of the given angle is 40 degrees.
Answer: 1
Step-by-step explanation:
Answer:
Step-by-step explanation:
-x - 1 = x + 3
-2x - 1 = 3
-2x = 4
x = -2
y = -2 + 3
y = 1
(-2, 1)
