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:
They changed 5m into a positive when it should've stayed as a negative until you isolate the variable m at the end, making m actually equal -7.
Step-by-step explanation:
-5m - 16 = 19
-5m = 19 + 16
-5m = 35
m = 35/-5
m = -7
First, divide the percent by 100. Then if the percent is not a whole number, then multiply the top and bottom by 10 for every number after the decimal point. :)
