What is the LCM of 30 and 70

210

Step-by-step explanation:

LCM means lowest common multiple

Step 1 : write out multiples of 30

30 X 1 = 30

30 X 2 = 60

30 X 3 = 90

30 X 4 = 120

30 X 5 = 150

30 X 6 = 180

30 X 7 = 210

30 X 8 = 240

Step 2: write out multiples of 70

70 X 1 = 70

70 X 2 = 140

70 X 3 = 210

70 X 4 = 280

Step 3 : the lowest multiple of 30 and 70 that are common to each other is 210

Hence, the LCM of 30 and 70 is 210

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
