Answer: ∠A = 70°

because ABC is an isosceles triangle and AB = AC

=> ∠B = ∠C = 55°

=> ∠A = 180-(∠B + ∠C) = 180° - 55°.2 = 70°

Find the length of side x in simplest radical form with a rational denominator.

Sauron [17]

Answer:

$\frac{11\sqrt{2}}{2}}$ or 5.5√2

Step-by-step explanation:

We can see that this is a 45-45-90 triangle

refer to the image below to see what that means

we can see that (in the image) 11=x√2

which means that x= 11/√2

to rationalize this fraction we mulitply both sides by √2 to get

$\frac{11\sqrt{2}}{2}}$ or 5.5√2
