The triangle ABC and the triangle BCD are similar, therefore

\dfrac{3+9}{x}=\dfrac{x}{9}\ \ \ |cross\ multiply\\\\x^2=12\cdot9\\\\x^2=108\to x=\sqrt{108}\\\\x=\sqrt{36\cdot3}\\\\x=\sqrt{36}\cdot\sqrt3\\\\\boxed{x=6\sqrt3}

Can anyone please help me to do this with steps

Answer:

x = 58°

Step-by-step explanation:

ABCD is a cyclic quadrilateral and opposite angles are supplementary , so

∠ DAB = 180° - 121° = 59°

The angle between a tangent and a chord is equal to the angle in the alternate segment, then

∠ ABD = 63° , thus

x = 180° - (59 + 63)° = 180° - 122° = 58°

C=85x+60<br> solve for x
Tatiana [17]
To solve for x:

<span>C=85x+60                  subtract 60 from both sides
</span>
<span>C - 60=85x+60 - 60

C - 60 = 85x              now divide by 85 both sides

(C - 60)/85 = x


So we can write:
x= \frac{C-60}{85}



</span>

I hope that helps!
