Find the lengths of the missing sides in the triangle. Write your answers as integers or as decimals rounded to the nearest tenth.

O x = 3.5, y = 5
O x = 5, y = 5
O x = 7.1, y = 5
x = 4.3, y = 5

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
