Answer:angle x=5
Step-by-step explanation:
Sum of triangles =180 ,x+90+45+40=180, x+175=180 ,x =5
We have to factor becasue
area=legnth times width
area=4x^2+28x+49
area=(2x+7)(2x+7)
area=(2x+7)^2
legnth =width
we arent' given area so we can't solve
but, , since it is a squaer room, legnth=width so √area=legnth=width
5x+ 10= -4x -17
⇒ 5x+ 4x= -17 -10
⇒ 9x= -27
⇒ x= -27/9
⇒ x= -3
Final answer: x=-3~
24:15 would be the simplified version, if that's what you meant.
