Solve: За – 6 = -12 a =​

a=−2

Step-by-step explanation:

Let's solve your equation step-by-step.

3a−6=−12

Step 1: Add 6 to both sides.

3a−6+6=−12+6

3a=−6

Step 2: Divide both sides by 3.

3a /3 = −6 /3

a=−2

a= 2/5 or 0.4

Step-by-step explanation:

3a−6=−12a

Step 1: Add 12a to both sides.

3a−6+12a=−12a+12a

15a−6=0

Step 2: Add 6 to both sides.

15a−6+6=0+6

15a=6

Step 3: Divide both sides by 15.

15a/15=6/15

a=2/5

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
