Answer:

11a. m <1 = 131 12a. m <1 = 42

11b. m <2 = 49 12b. m <3 = 75

11c. m <3 = 131 12c. m <4 = 42

11d. m <4 = 49 12d. m <5 = 63

11e. m <5 = 131 12e. m <6 = 75

11f. m <6 = 49 12f. m <7 = 105

11g. m <8 = 49 12g. m <8 = 75

11h. m <9 = 92 12h. m <10 = 75

11i. m <10 = 88 12i. m <11 = 42

11j. m <11 = 92 12j. m <12 = 138

11k. m <12 = 88 12k. m <13 = 42

11l. m <13 = 92 12l. m <14 = 138

11m. m <14 = 88

11n. m <15 = 92

Step-by-step explanation:

When lines are parallel to each other than:

Corresponding Angles are equal.

Alternate Interior Angles are equal.

Alternate Exterior Angles are equal.

Consecutive Interior Angles add up to 180 degrees.

You can check some math websites for definitions of these angle relationships.

A square park is 75 m long. Find the area of the park.<br>

Inga [223]

5625 m^2

If is is square, all sides must be congruent (all sides are 75m). To find area, you multiply width x length (how long). Therefore:

75m x 75m = 5626 m^2

A woman starts out walking due north for 2 miles, and then she turns due west and continues for another 2 miles. How far from he

Mrac [35]

For this case we can model the problem as a rectangle triangle.
We have:
Length of the sides of the triangle.
We want to find:
Length of the hypotenuse.
Using the Pythagorean theorem we have:
$d ^ 2 = 2 ^ 2 + 2 ^ 2
$
$d = \sqrt{2 ^ 2 + 2 ^ 2} 

d = \sqrt{4 + 4} 

d = \sqrt{8} 

d = 2\sqrt{2} 
$
Answer:
She is:
$d = 2\sqrt{2}$
miles far from her starting point

Answer:

m∠3 = 24°

Step-by-step explanation:

By the theorem,

"Intercepted arc measures the double of the inscribed angle formed by two chords meeting at one point of the circle."

In the given picture,

∠3 is the inscribed angle subtended by the arc ED and is the intercepted arc.

Therefore, m∠3 = $\frac{1}{2}m(\text{arc}ED)$
