2x + 3x + 5x = 180
10x = 180
x = 18
2x = 36, 3x = 54, 5x = 90
They add up to 180 (definition of sum of angles of a triangle.)
Let x be the first number
X + 1 be the second number
So
(x+1)^2 – x^2 = 2017
X^2 + 2x +1 – x^2 = 2017
2x + 1 = 2017
2x = 2017 – 1
2x = 2016
X = 1008
X + 1 = 1009
Sum = 1008 + 1009 = 2017
Answer: E = 56
Step-by-step explanation:
E is proportional to √C
To remove proportionality, introduce a constant (k).
E = k × √C
From question,
E = 40 and C = 25
So,
40 = k ×√25
40 = k × 5
k = 8
Now,
C = 49
k = 8
E = ?
E = k√C
E = 8 × √49
E = 8 × 7
E = 56
