Answer:

m<Y = 68°

Step-by-step explanation:

A tangent drawn to a circle makes a 90° angle with the radius that intersects it at the point of tangency. That means that m<X = 90°.

The sum of the measures of the angles of a triangle is 180°.

m<X + m<Y + m<Z = 180

90 + m<Y + 22 = 180

m<Y + 112 = 180

m<Y = 180 - 112

m<Y = 68

Convert 11.42424242 to a rational expression

ki77a [65]

Well, $11.42424242$ is a rational expression already. Of course:
$11.42424242 = 11+\dfrac{42424242}{10^8} = \dfrac{1142424242}{10^8}$ .

But maybe you mean $11.\overline{42} = 11.4242\dots$ So:
$x = 11.\overline{42} \iff 100x = 1142.\overline{42} \iff 99x = 1131 \iff x = \frac{1131}{99} = \frac{377}{33}$
