Answer:
If you need to find out what x is, it would be -5
Step-by-step explanation:
10-15=x and so x is -5
If two adjacent angles have their exterior sides in perpendicular lines, then the two angles are also perpendicular.
Both exterior and interior angles sum up from 90 - 180 degrees. Therefore, if an exterior angle is perpendicular, then the interior angle must also be perpendicular in order for them to sum up to that amount of degrees (90 - 180).
Answer:
A
Step-by-step explanation:
Perimeter = the sum of all side lengths
Perimeter =
Perimeter = 15 (in this case)
so...
And we're trying to solve for x.
Step 1. Subtract 6 to both sides
Step 2. Add 3 to both sides
Step 3. Combine like terms
Step 4. Solve for x
The answer for this question is A
