Ineed on the third one at the bottom ‍♀️

angle k>angle r

Step-by-step explanation:

the two sides are equal in the given two triangles, the two pairs of corresponding angles are equal. since the third side of triangle JKL is greater than the third side of triangle PQR, the angles opposite to them would also be respectively greater. so angle K is greater than angle R

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
