Answer 2

Answer:

$tan \: a = \frac{21}{20}$

hope it will clear to u....keep learning

Step-by-step explanation:

$cosa = \frac{base}{hypotneus} = \frac{20}{29}$

by comparing get

base = 20 unit

hypotenus = 29 unit

by pythagoras theorem i.e,

hypotenus² = base² + perpendicular²

(29)² = (20)² + perpendicular²

$perpendicular = \sqrt{ {29}^{2} - {20}^{2} }$

$perpendicular = \sqrt{841 - 400}$

$perpendicular = \sqrt{441} = 21unit$

$tana = \frac{perpendicular}{base} = \frac{21unit}{20unit}$

$tan \: a = \frac{21}{20}$
