Ratio of 2 complementary angles = 4:5
Let first angle be 4x
Let second angle be 5x
Sum of two complementary angles = 90
4x + 5x = 90
9x = 90
x = 90/9 = 10
First angle = 4x = 4*10 = 40
Second angle = 5x = 5*10 = 50

Answer:
B. 2, -0.5
Step-by-step explanation:
Given the equation

Rewrite it as

Graph the graph of the quadratic function 
The grapg of this function is a parabola going downwards.
This parabola intersects the x-axis at points x = -0.5 and x = 2, so the solutions of the equation are x = -0.5 and x = 2
Answer: 14.83 inches
Explanation:
h² + 6² = 16²
h² = 16² - 6²
h² = 220
h = 14.83
