Answer:
Apply cosine rule:
c²=b²+a²-2ba cosC
C= pi/3 = 180/3 = 60 degrees
cosine 60 deg = 0.5
c²=2²+3²-[2×2×3×0.5]
c²=7
c=√7
c=2.645 ;length of third side of angle
Step-by-step explanation:
-7x-3=25 (combine like terms)
-7x= 28 (add 3 on both sides)
x= -4 (divide -7 on both sides
Answer:
6x+36=180
6x=144
x=24
