Ответ:
sin(x) and cos(y) are equal and have ratio of 1 : 1
First find the missing hypotenuse using Pythagoras theorem:
a² + b² = c²
12² + 5² = c²
c = √144+25
c = 13
using sine rule:
using cosine rule:
Ответ:
As, we are given a right angled triangle with two sides 12 and 5, we can find the third side using Pythagoras theorem ,i.e,
Using trigonometric identities:
Ⲧⲏⲉⲅⲉ⳨ⲟⲅⲉ,For sin x , we have ,
Perpendicular = 5 Hypotenuse = 13Base = 12ㅤ
For cos y , we have ,
Perpendicular = 12Hypotenuse = 13Base = 5Ответ:
B) 3/5
Explanation(Make that Brainlest if it's right)
P(4+odd n)= 1/10 + 5/10 = 6/10 = 3/5
