1/10 * 4/10 = 4/100 divide both by 4 it'll be 1/25
        
             
        
        
        
Answer:
its 210
Step-by-step explanation:
area of rect is 20×12=240
tri angle area=1/2×5×12=30
so 240-30=210

X^2+12x+6=0  subtract 6 from both sides...
x^2+12x=-6  halve linear coefficient, square it, and add it to both sides...
x^2+12x+36=30  now the left side is a perfect square...
(x+6)^2=30  take square root of both sides...
x+6=30^(1/2)  subtract 6 from both sides...
x=-6-30^(1/2) and -6+30^(1/2)
        
             
        
        
        
 Answer:
AR is 3 using Pythagoras 5^2 - 4^2 = 3^2. sin R is just sin (AC/RC). cos is adjacent over hypoteneus. tan is oppositve over adjacent. and sec is 1/cos, csc is 1/sin, and cot is 1/tan.
