Hello!

You use the Pythagorean theorem to solve this

$a^{2} + b^{2} = c^{2}$

Put in the values it tells you to

$a^{2} + 4.4^{2} = 5.5^{2}$

Square the numbers

$a^{2} + 19.36 = 30.25$

Subtract 19.36 from both sides

$a^{2} = 10.89$

Take the square root of both sides

a = 3.3

The answer is 3.3

Hope this helps!

What is the value of a?

Answer:

$\huge\boxed{a=\dfrac{16}{3}=5\dfrac{1}{3}}$

Step-by-step explanation:

$\triangle ZYW\sim\triangle WYX\ (AAA)\\\\\text{Therefore corresponding sides are in proportion}\\\\\dfrac{YX}{YW}=\dfrac{YW}{ZY}\\\\\text{substitute}\\\\YX=a;\ YW=4;\ ZY=3\\\\\dfrac{a}{4}=\dfrac{4}{3}\qquad\text{multiply both sides by 4}\\\\4\cdot\dfrac{a}{4}=4\cdot\dfrac{4}{3}\qquad\text{cancel 4}\\\\a=\dfrac{16}{3}$
