Answer:
If the sinø=7/12, cosø is 
Step-by-step explanation:
We are given sinФ = 7/12
We need to find cosФ
The basic trigonometric functions of right triangle are:


We need values of adjacent and hypotenuse to find cosФ
Using Pythagoras theorem we can find the value of adjacent

We have Hypotenuse= 12 and Opposite = 7 (because
and we are given 
Inserting values and finding adjacent:

So, value of Adjacent is 
Now finding cosФ

Adjacent =
, hypotenuse = 12

So, If the sinø=7/12, cosø is 
Answer:
B) 5.8
Step-by-step explanation:
5^2 + 3^2 = x^2 ( By Pythagoras theorem )
25 + 9 = x^2
34 = x^2
x = 5.8
