18). <br><br> Find mZBCA.<br> B<br> (5x + 12)<br> [.<br> (9x + 1)<br> А<br> (10x – 37)°
makkiz [27]

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°
