Answer:
The solution is .
Step-by-step explanation:
Given:
The inequality given is:
In order to simplify for 'x', we first isolate 'x' on one side.
Adding -4 on both sides, we get:
Now, is an absolute value function which is defined as:
Therefore, the given inequality can be rewritten as:
and
Therefore, the solution is .
Answer:
z = 69°
Step-by-step explanation:
The sum of all interior angles in a quadrilateral is 360°, and a right angle is worth 90°. We're given the values of the interior angles as 90, 122, 79, and z degrees.
Step 1: Combine like terms.
Step 2: Subtract 291 from both sides.
Step 3: Check if solution is correct.
Therefore, z = 69°.
