Answer: y1= logx/log2 and y2=logx/log12 (B and C)
Step-by-step explanation:
Answer:
Step-by-step explanation:
12x-20=6(x-20)-9x
Opening bracket
12x - 20 = 6x - 120 - 9x
Collecting like terms
12x - 6x + 9x = -120 + 20
15x = -100
Dividing by 15
15x/15 = -100/15
x = -20/3
x = - 6 2/3
10 ft
4 sides
10x4=40
Perimeter=40 ft
Num. 4 no because 5t2 doesn't equal 10 …or equals7
Ok
First use the sine rule to find one value
b / sin B = c / sin C
20.2 / sin B = 18.3 / sin 38
sinB = 20.2 * sin 38 / 18.3 = 0.6796
m < B = 42.8 degrees
the other possible measure is 180 - 42.8 = 137.2 degrees
