Answer:
m∡BCA = 57°
Step-by-step explanation:
find 'x' by adding all expressions and setting them equal to 360°
9x+1 + tx+12 + 10x-37 = 360
24x = 384
x = 16
Substitute 16 into 10x-37
160 - 37 = 123
m∡BCA is supplemental with 123°, therefore it measures 57°
First,
|-13| represents the absolute value of the number 13. Absolute values cannot be negative. So |-13| cannot become -13, it would become 13.
So,
|-13| - |13| = -13 - 13 = 26 would become
|-13| - |13| = 13 - 13 = 0
