A lawn is in the shape of a right angled triangle. the lengths of the 2 shorter sides are (x+2) meters and (4x+4) meters while the length of the hypotenuse is (5x) meters. form and solve an equation in x and find the area of the lawn in metres squared

x=5 ; Area= 84m²

Step-by-step explanation:

(x+2)²+(4x+2)²=(5x)²

x²+4+4x+16x²+16+32x=25x²

8x²-36x-20x=0

x=5;x=-1

hypotenuse should be positive

x=5

area=lxb/2

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
