Answer 1

Answer:

sorry I didn't understand what you want to say

Answer 2

The triangular sign  board DRY with  right-angled at R is  used to display some  slogan to it.

Given,

∠ R = 90°

DR = 5 cm

RY + DY = 25 cm

Since ∠ R is a right angle, so DY is the hypotenuse.

⇒ DY > RY

here, we use pythagorean triplet 5, 12, 13

as, DR = 5 cm (given)

RY = 12 cm (as DY > RY)

DY = 13 cm

The values of sinD cos D tan D​ are,

sin D = RY/DY = 12/13

cos D = DR/DY = 5/13

tan D = RY/DR = 12/5
