Answer:

$m$ ∠8 = 65°

Step-by-step explanation:

The other side (angle) of 115 is $n$ and $n =$ ∠8

To find $n$ you need to subtract 180 - 115 giving you 65, and since n is angle 8, angle 8 is also 65 since the angles have a state of congruence...

Answer: 65 degrees

Explanation:

The adjacent angle directly above angle 8 is congruent to the 115 degree angle (due to the corresponding angles theorem). This only works because p || q and q || r, so by the transitive property of parallel lines, we know that p || r.

Since the 115 degree angle and angle 8 pair up to form a straight line, we know that the two angles must add to 180 degrees

115+(angle 8) = 180

angle 8 = 180 - 115

angle 8 = 65 degrees

Consider each of the following relationships. Which school shows the greatest rate of change between male and female students?

ratelena [41]

Answer:

The school C shows the greatest rate of change between male and female students

Step-by-step explanation:

Let

x -----> the number of female students

y ----> the number of male students

we know that

The ratio of male students to female students is

$\frac{y}{x}$

we have

School A

$\frac{y}{x}=\frac{4}{1}=4$

School B

$\frac{y}{x}=\frac{4}{3}=1.33$ ----> the slope of the linear equation

School C

$\frac{y}{x}=\frac{1,260}{280}=4.5$

$4.5 > 4 > 1.33$

therefore

The school C shows the greatest rate of change between male and female students

Triangle LMN is located at L(2,3), M(1,2), and N(4,4). The triangle is then transformed using the rule (x+5, y+2) to form the im

charle [14.2K]

Using the rule (x+5, y+2) you would add 5 to the x value and 2 to the y value so the answer would be L' (7,5) M' (6,4) N' (9,6)

Find the value of x ? A)67 B)113 C)77 D)57

lana [24]

Answer:

Step-by-step explanation:

The sum of the angles measures at one side of the parallelogram is 180°.

Therefore we have the equation:

x + 113 = 180 subtract 113 from both sides

x + 113 - 113 = 180 - 113

x = 67
