Find the angle measures. Justify your responses.

MatroZZZ [7]

Answer:

m∠3 = 2x - 10° and m∠6 = 3x + 20

m∠3 = 58° ; m ∠6 = 122°

Step-by-step explanation:

a ║ b

m∠2 = m∠6 If ║ cut by a transversal, then corresponding angles

are ≅ and =

m∠7 = m∠3 If ║ cut by a transversal, then corresponding angles

are ≅ and =

m∠2 = 3x + 20 Given

m∠7 = 2x - 10 Given

m∠6 + m∠3 = 180° If ║ cut by a transversal, then each pair of same-side

interior angles (also called consecutive interior angles

are supplementary (sum = 180°) .

3x + 20 + 2x - 10 = 180°

5x + 10 = 180°

5x = 170°

x = 34°

Answer: m∠3 = 2x - 10° and m∠6 = 3x + 20

m∠3 = 2(34) - 10 ; m∠6 = 3(34) + 20

m∠3 = 58° ; m ∠6 = 122°

The average swimming pool has a water capacity of 375,000 liters. Use dimensional analysis to show how many milliliters of water

Agata [3.3K]

Answer:

375,000,000 milliliters of water is in the pool.

Step-by-step explanation:

We know

1 liters = 1000 milliliters

hence to convert liter in to milliliter we have to multiply the liter unit with 1000 to get the milliliter

we have to find value of 375,000 liters in milliliters

to get that we multiply both side by 375,000

1* 375,000 liters = 1000* 375,000 milliliters

thus,

375,000 liters = 375,000,000 milliliters

thus, there is 375,000,000 milliliters of water is in the pool.

The length of a board is 30.75 inches. Bradley cut the board into 3 smaller pieces that were all the same length. Which expressi

Harman [31]

Answer:

The length of each smaller piece, l=L/n inches

Step-by-step explanation:

This can be expressed as;

Total length=Length per piece×number of pieces

where;

The total length=L

length per piece=l

number of pieces=n

Substituting in the equation;

L=l×n

To get the length of each smaller piece;

l=L/n inches

solving;

l=30.75/3=10.25 inches
