Hi there, so we know that all triangles add up to 180 degrees so we will take 38 and add it with 25 to get 63 then we subtract 180 by 63 to get 117 which is your awnser!! I mean I might be wrong but I’m probably right. I hope this helps!! Have a great morning, night, or day, Whatever it is for you!

Answer:
Step-by-step explanation:
We need to perform the folowing operation:
×
Factorizing we have:
×
Simplifying, we get:
Answer:
Inequality:
Set Notation:
Interval:
Step-by-step explanation:
Given
The Attached Number Line
Solving (a): The Inequality
i. On the number line, we notice that a thick line starts at number 3 and points to the right
ii. Also, there is a closed circle on number 3.
(i) & (ii) indicates that
Solving (b): Set Notation
The set notation that indicates is
Solving (c): The interval notation
The inequality implies that x starts from 3 and moves towards +infinity
The means that 3 is inclusive of the inequality
Hence:
The interval notation is
