Answer:
cos N = 7/25 =.28
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adj side / hypotenuse
cos N = MN/ LN
We need to find the ad
Using the Pythagorean theorem
a^2+b^2 = c^2
MN^2 + 48^2 = 50^2
MN^2 + 2304 =2500
MN^2 = 2500-2304
MN^2 =196
Taking the square root
MN =14
cos N = MN/ LN
cos N = 14/50
cos N = 7/25

Step-by-step explanation:
P=5/12×2/12=5/72
Answer: width = 72.50 m
Step-by-step explanation:
P = 2l + 2w
425 = 2( 140 ) + 2w
425 - 280 = 2w
145 = 2w
w = 72.50
