Answer:

70° is the answer hope it helps

30°+90°+ 3y= 180°

120°+3y= 180°

3y= 180°-120°

y= 60°/3

y= 20°

Now

y°+90°+x°= 180°

20°+90°+x= 180°

x= 180°-110°

Find the value of x number on top is 6 and other is 9

faltersainse [42]

Answer:

x = - 12, 3

Step-by-step explanation:

By tangent secant theorem:

$x(x + 9) = {6}^{2} \\ \\ {x}^{2} + 9x = 36 \\ \\ {x}^{2} + 9x - 36 = 0 \\ \\ {x}^{2} + 12x - 3x - 36 = 0 \\ \\ x(x + 12) - 3(x + 12) = 0 \\ \\ (x + 12)(x - 3) = 0 \\ \\ x + 12 = 0, \: \: x - 3 = 0 \\ \\ x = - 12, \: \: x = 3 \\ \\$
