Answer:
The answer to your question is: ∠K = 138°
Step-by-step explanation:
m∠N = 42°
m∠K = ?
The sum of all the internal angles in a quadrangle equals 360°
then
∠N + ∠L + ∠M + ∠K = 360°
∠N = ∠ L and ∠M = ∠K
So, 2 ∠N + 2 ∠K = 360
Substitution
2 (42) + 2 ∠K = 360
84 + 2 ∠K = 360
2 ∠K = 360 - 84
2 ∠K = 276
∠K = 276 / 2
∠K = 138°
Step-by-step explanation:
48 us the correct answer
1.6 is in between those 2 numbers
Answer:
The slope is 3/8!
Explanation:
You put your equation in slope-intercept form, that is how you find the slope.
3x-8y=-20
-8y=-3x-20
y=3/8x-20
the fraction is now positive because the numerator and the denominator are both negative so they are changed into positive.

4.)
To solve for Y it is To solve for X
-8y=-6x -8y=-6x
/-8 /-8 /-6 /-6
y=3/4(x) 4/3(y)=x
5.)
to solve for Y To solve for X
1/2(y)=4(2x-1/4) 1/2(y)=4(2x-1/4)
1/2(y)=8x-1 /4 /4
*2 *2 y/8=2x-1/4
+1/4 +1/4
y=16x-2 (y/8)+1/4=2x
/2 /2
((y/8)+1/4)/2=x
