What is the ratio of 24

Are two pairs of congruent angles enough information to conclude that two triangles are similar explain

katen-ka-za [31]

Yes, because if two angles of a triangle are equal, then the third angle must also be equal, because angles of a triangle always add to make 180°.

Find the value of x on this triangle

blondinia [14]

Look at the picture.

ΔABD and ΔBCD are similar, therefore:

$\dfrac{y}{5}=\dfrac{11}{y}\ \ \ |\cross\ multiply\\\\y^2=55\to y=\sqrt{55}$

Use Pythagorean theorem:

$x^2=5^2+(\sqrt{55})^2\\\\x^2=25+55\\\\x^2=80\to x=\sqrt{80}\\\\x=\sqrt{16\cdot5}\\\\x=\sqrt{16}\cdot\sqrt5\\\\\boxed{x=4\sqrt5}$
