Question

Hey there! I know this is prob really simple and I am beginning to understand it, but my problem isSec 60°Now I know all the SOH CAO TOH stuff, and things like that, I just don't understand how to find the value because it changes all the time with the right triangle and the number of their sides. Really just need the formula on how to solve stuff.

Answer 1

Formula to solve a triangle

Lets begin with

Tan 45

is a right traingle, with angles 45,45 and 90°

Then, to find Tan 45

Tan 45= [√(1^2) + (1^2) ]/2 = √2/2

Tan 45= √2/2

NOW find Sec 60°

Sec 60° = 1/Sin 60°

Sin 60°is found by a triangle, with angles 30,60,90

Sin 60°= √3/2 , thats because
