Question

What is the value of x in this figure? 52√ 53√ 103√3 5

Answer 1

Using the law of cosin

cos(angle) = adjacent leg / hypotenuse

We fill in what we know and solve for x:

cos(30) = x / 10

x = cos(30) * 10

x = 5 SQRT(3) 

Answer 2

Answer:

cos(angle) = adjacent leg / hypotenuse

We fill in what we know and solve for x:

cos(30) = x / 10

x = cos(30) * 10

x = 5 SQRT(3)  

Step-by-step explanation:

cos(angle) = adjacent leg / hypotenuse

We fill in what we know and solve for x:

cos(30) = x / 10

x = cos(30) * 10

x = 5 SQRT(3)
