B. 30 degrees
All of the sides should add up to 180 because it is a triangle, so 100 + 50 = 150. 180 - 150 = 30
The interval notation is { 5/ 2 < x > 0 }
<h3>How to determine the value</h3>
Given the inequalities;
To determine the value of x, we have;
2x - 1 < 4
collect like terms
2x < 4 + 1
2x < 5
Make 'x' the subject
x < 5/ 2
−5x −3 > −3
collect like terms
-5x > -3 + 3
-5x > 0
x > 0
Thus, the interval notation is { 5/ 2 < x > 0 }

No, because you would have to simplify like terms. Which the simplest form would be
5x-4
