9/26 is the correct answer
Answer:
Hi there!
Your answer is:
The length is 75
Step-by-step explanation:
P=180
L=5w
Perimeter formula
L+L+W+W=P
Plug in known values
5W+5W+W+W=180
12W=180
/12
W=15
Plug in width in length formula!
L=5W
L=5(15)
L=75
Ok, so in the problem there are 5 angles given but you really only need to focus on <KNL and <MNL. these two angles are a linear pair, or supplementary, which means that they add up to 180˚. so, if <KNL is 38˚, then <MNL is 142˚. 180-38=142
hope this helped
Answer:
x = 6
y = -1
Step-by-step explanation:
-2x + 5y = -17 ------ equation 1
3x- 10y = 28 ------- equation 2
equation 1× 2
-4x + 10y = -34 ------- equation 3
equation 2 + equation 3
-x = -6
x = 6
x = 6 substitute for equation 1
-12 + 5y = -17
5y = -5
y = -1
