Answer: all of them are correct! great job!!!1
Step-by-step explanation:
.4 is 40 percent because you move the decimal two spaces to the right so it would be 40 percent, same as the others!
m∠X + m∠Y < 90° is true.
<h3>How to solve it?</h3>
XYZ is a triangle.
We have to find the option that is true about △XYZ.
By angle sum property of a triangle,
The sum of all the interior angles of a triangle is always equal to 180°.
So, ∠X + ∠Y + ∠Z = 180°
Given, m∠Z > m∠X + m∠Y.
This implies that ∠Z is greater than the sum of the angles ∠X and ∠Y.
so, ∠X + ∠Y must be less than 90°.
Hence, we can say that ∠X + ∠Y < 90°

Answer:
If
or
, there is only one solution to the given quadratic equation.
Step-by-step explanation:
Given a second order polynomial expressed by the following equation:

This polynomial has roots
such that
, given by the following formulas:



The signal of
determines how many real roots an equation has:
: Two real and different solutions
: One real solution
: No real solutions
In this problem, we have the following second order polynomial:
.
This means that 
It has one solution if




We can simplify by 8

The solution is:
or 
So, if
or
, there is only one solution to the given quadratic equation.
