Answer:
x = 47
Step-by-step explanation:
Every triangle's interior angles add up to 180°.
Let's make an equation.
x + 102 + 31 = 180
x + 133         = 180
x                   = 47

11 as many fiction books as non fiction.
Fiction books F,  Non Fiction NF
F: NF =  11 : 1
Total ratio 11+ 1 = 12.
Fraction of Fiction books F,  =  11/12
Total books = 312.
Fiction books  =     11/12 * 312 =  286
Fiction books = 286

Answer:
3x - 5
Step-by-step explanation:
Given that f(x) = 5x - 2 and g(x) = 2x+3
f(x) - g(x) = 5x-2 - (2x+3)
Expand
f(x) - g(x)  = 5x - 2 - 2x - 3
Collect like terms
f(x) - g(x) = 5x - 2x -2-3
f(x) - g(x)  = 3x - 5
Hence the required answer is 3x - 5
