Your question is quite incomplete: who's k?
Anyway, I'm assuming that this is one of those question about variation. If x and y are in proportion, we have
If x and y are in inverse proportion, we have
Answer:
∠J = 115
∠N = 65
∠M = 50
∠K = 130
Step-by-step explanation:
Sum of all the angles = 360
2x + 15 + x + 15 +x + 3x - 20 = 360
Combine like terms
2x + x + x + 3x + 15 + 15 - 20 = 360
7x + 10 = 360
7x = 360 - 10
7x = 350
x = 350/7
x = 50
∠J = 2x + 15 = 2*50 + 15 = 100+15 = 115
∠N = x +15 = 50 +15 = 65
∠M = x = 50
∠K = 3x - 20 = 3*50 - 20 = 150 - 20 = 130
Answer:
22/35
Step-by-step explanation:
3/7 + 1/5
First, find a common denominator.
7*5=35 multiply the numerator by 5 too: 3*5=15
5*7=35 multiply the numerator by 7 too: 1*7=7
15/35 + 7/35
=22/35
Cannot be simplified.
