Answer:19/30

Step-by-step explanation:

1. multiply and divide(left to right)-1/6

=-1/6+4/5

2.multiply and divide(left to right)4/5

=-1/6+4/5

3. add and subtract(left to right)-1/6+4/5=19/30

=19/30

In triangle NQL, point S is the centroid, NS = (x + 10) feet, and SR = (x + 3) feet.

olya-2409 [2.1K]

Where R is the median between Q and L:

From my understanding of a triangle's centroid, it divides an angle bisector into parts of 2/3 and 1/3. In the given problem, these divisions are NS and SR. Therefore, twice SR would be equal to NS. From here, we can get the value of X, to solve for SR.

NS = 2SR
(x + 10) = 2(x + 3)
x + 10 = 2x + 6
x = 4

Therefore, SR = (x + 3) = 7

What must be true for lines a and b to be parallel lines? Check all that apply

iren [92.7K]

the question does not present the options, but this does not interfere with the resolution

we know that

if a and b are parallel lines

1) m∠2=58°------> by corresponding angles

2) m∠1=4x-10------> by alternate exterior angles

3) [m∠2+m∠(3x-1)]+m ∠1=180°------> by supplementary angles

58+(3x-1)+4x-10=180

7x=180-47

7x=133

x=19°

4) angle (4x-10)=-4*19-10-------> 66°

5) angle 3x-1=3*19-1-------> 56°
