<h3>
<u>Given</u><u>:</u><u>-</u></h3>
- The hypotenuse of a right angle triangle is 13cm.
- One other side of the triangle is 1cm shorter than the hypotenuse.
<h3>
<u>To</u><u> </u><u>find</u><u> </u><u>out</u><u>:</u><u>-</u></h3>
Find the third scale of the triangle .
<h3>
<u>Solution:-</u><u> </u></h3>
Let the third Side be x.
According to the question,
★ Hypotenuse = 13 cm
★ Other side = Hypotenuse - 1 [ Given ]
= 13 cm - 1 cm
= 12 cm
Now,
<u>By pythagoras theorem</u>,
13² = 12² + x²
⇒ 169 = 144 + x²
⇒ x² = 169 - 144
⇒ x² = 25
⇒ x = √25
⇒ x = 5 cm
Hence, the third scale of the triangle is 5 cm.
Solution:
(tanx + tany)/(1-tanxtany) is equal to the formula of tan(x+y)
sinxcosy + cosxsiny = is equal to the formula of sin(x+y)formula
cosxcosy - sinxsiny) = is equal to the formula of cos(x+y)
So this means that
tan(x+y) = sin(x+y)/cos(x+y)
