Answer:

AB = 5.6 cm

Step-by-step explanation:

From the question given above, the following data were obtained:

Angle θ = 62°

Hypothenus = BC = 12 cm

Adjacent = AB =?

The lenght of side AB can be obtained by using Cos θ ratio. This is illustrated:

Cos θ = Adjacent / Hypothenus

Cos 62 = AB / 12

0.4695 = AB / 12

Cross multiply

AB = 0.4695 × 12

AB = 5.6 cm

Thus, length AB is 5.6 cm

Please help!! Show work please!!
Nonamiya [84]

1. 3x - 2y = 8 Subtract 3x on both sides

-2y = 8 - 3x Divide by -2 on both sides to get y by itself

y = -4 + 3/2x


2. a + b / 3 = 5 Multiply 3 on both sides

a + b = 15 Subtract a on both sides to get b by itself

b = 15 - a


3. 12x - 4y = 20 Subtract -12x on both sides

-4y = 20 - 12x Divide -4 on both sides to get y by itself

y = -5 + 3x


4. y + 3 = -5(x - 2) Multiply -5 to (x-2)

y + 3 = -5x + 10 Subtract 3 on both sides to get y by itself

y = -5x + 7
