Find the value of the missing trigonometric ratio of each triangle? help me HURRY!!!

The value of cosA = (√3)/2 and tanA = 1/√3 or (√3)/3.

Step-by-step explanation:

Firstly, you have to find the value of adjacent using Pythogoras' Theorem, a² = b²+c² :

Let a = 2, b = 1

2² = 1² + c²

c² = 2² - 1²

= 4 - 1

= 3

c = √3

Now we have found the adjacent so we can find cosA and tanA using Trigonometric function, cosθ = adj./hypo. and tanθ = oppo./adj. :

adj. = √3

oppo. = 1

hypo. 2

cosA = (√3)/2

tanA = 1/√3 OR (√3)/3

answer: its because of life

step-by-step explanation: i dont know

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
