Answer:
mZB= 74
Step-by-step explanation:
ZB+ZA=180
3X-23+2X-12=180
5X-35=180
5X=180+35
5X=215 (then divide both sides by 5 to x be left alone.)
X=43....so ZB=2(43)-12
=86-12=74
5 + 3 = 2/7p - 115 + 3 = 2p/7 - 11
8 = 2p/7 - 11
8 + 11 = 2p/7
19 = 2p/7
19 × 7 = 2p
133 = 2p
133/2 = p
p = 133/2
The answer is: p = 133/2 or p = 66.5.
