Answer:

y=\frac{22}{\sqrt{2} }

x= 19

Step-by-step explanation:

sen 45 =\frac{11}{y}

y=\frac{11}{sen 45}

y= \frac{11}{\frac{\sqrt[]{2} }{2} }

y=\frac{22}{\sqrt{2} }

y^{2} =x^{2}  +11^{2}

x^{2} =y^{2}-121

x^{2}= (\frac{22}{\sqrt{2}  }) ^{2}  + 121

x^{2} = \frac{484}{2} +121

x^{2} =242+121

x=\sqrt{363}

x= 19

What is Meant by Significant Figures?

In Mathematics, the significant figures define the number of important single digits that contribute to the degree of accuracy of the given number. The five important rules for the significant figures are as follows:

All the non zero numbers are significant figures

The zero present in between the non zero numbers are significant figures

The leading zeros are not significant

The trailing zeros present at the right side of the decimal point are significant figures

Trailing zeros of the number without a decimal point are not significant figures

The trailing zeros present in the whole number with the decimal point are significant figures
