kvasek [131]

9514 1404 393

Answer:

  ∠4 = 45°

Step-by-step explanation:

Angles 1, 2, and 4 are all congruent.

  ∠4 = ∠2

9 exponent 10<br> Divide by 9 exponent 11
Natasha_Volkova [10]

Answer:

\frac{\sqrt{110} }{11} or \frac{\sqrt{10} }{\sqrt{11} }

Step-by-step explanation:

I assume you mean \frac{9\sqrt{10} }{9\sqrt{11} }

there is a common factor of 9 in the numerator and denominator so we can cancel out to form \frac{\sqrt{10} }{\sqrt{11} }

\frac{\sqrt{10} }{\sqrt{11} } is technically a correct answer, but I will go ahead to rationalize the denominator

multiply \frac{\sqrt{10} }{\sqrt{11} } by some form of 1. this case, we will use \frac{\sqrt{11} }{\sqrt{11} } as our 1.

\frac{\sqrt{10} }{\sqrt{11} }*\frac{\sqrt{11} }{\sqrt{11} } = \frac{\sqrt{10} *\sqrt{11} }{\sqrt{11} *\sqrt{11} } = \frac{\sqrt{110} }{11}
