Answer:

Step-by-step explanation:
- Option A
tells us that: When we add 5 to a variable x, we get 20. As it has a unique value for x and is completely equal to it(i.e. 15), It is an equality.
- Option B
tells us that: A variable x equals to 5. Hence, as x is unique for 5 and is wholly equal to it, it's an equality too. - Option C
tells us that: A variable x isn't 5 but lesser than it. As we cannot equate it to 5, nor we are given the nature of the variable x, it is an Inequality. - Option D
is an expression; It can't be called an equation or an inequality unless we relate it with another expression.
Answer: x > 74
<u>Step-by-step explanation:</u>
An obtuse angle is greater than 180°. So, 3x - 42 must be greater than 180.
- 3x - 42 > 180
- <u> +42 +42</u>
- 3x > 222
- <u>÷3 ÷3</u>
- x > 74
