Use the diagram of the right triangle above and round your answer to the nearest hundredth.

Yakvenalex [24]

Answer:

value of a = 6.93 m

hence , (b.)

Step-by-step explanation:

the given triangle is a right angled triangle, so

by using trigonometry.

=》

$\tan(a) = \tan(30) = \frac{1}{ \sqrt{3} }$

and we know,

=》

$\tan(a) = \frac{a}{b}$

so, by above values of tan ( a ) we get,

=》

$\frac{a}{b} = \frac{1}{ \sqrt{3} }$

=》

$\frac{a}{12} = \frac{1}{ \sqrt{3} }$

=》

$a = \frac{12}{ \sqrt{3} }$

=》

$a = 4 \sqrt{3}$

=》

$a = 6.93$

hence, a = 6.93 m
