If |lm and m&lt;6 = 4x - 15 and m&lt;7 = x+30, then m&lt;6 =<br> 35<br> 45<br> 39<br> 15
pentagon [3]

Answer:

∠ 6 = 45°

Step-by-step explanation:

∠ 6 and ∠ 7 are alternate angles and are congruent, thus

4x - 15 = x + 30 ( subtract x from both sides )

3x - 15 = 30 ( add 15 to both sides )

3x = 45 ( divide both sides by 3 )

x = 15

Thus

∠ 6 = 4x - 15 = 4(15) - 15 = 60 - 15 = 45°

The area of a square is 49 cm^2. What is the perimeter, in cm, of the square?
rewona [7]

Answer:

P = 28 cm

Step-by-step explanation:

The area of a square is

A = s^2 where s is the side length

49 = s^2

Taking the square root of each side

sqrt(49) = sqrt(s^2)

7 =s

Now find the perimeter of the square

P = 4s

P = 4(7)

P = 28 cm
