ACT/SAT Dontrell’s school has a rectangular lawn with the dimensions shown. Students often walk along the diagonal of the lawn as a shortcut. To the nearest tenth of a meter, how much shorter

is it to walk directly from J to L rather than from J to K to L?

JK = 16 m

JM = 6 m

step-by-step explanation:

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

jml angle lkj & angle mj = lm
