Question

What is tan R? And what’s the answers??

Answer 1

Since both the triangles are similar therefor there angle are equals

angle E = angle A

angle D = angle C

angle F = angle R

In right triangle DEF first find out the side DE with the help of pythagoras theorem

H² = P² + B²

13² = P² + 12²

169-144= P²

p²= 25

P = 5 ft

hence tanR=tanF= perpendicular/ base= 5/12
