Learn to find the missing angles for a triangle using inverse trig functions

👉 Learn how to find a missing angle of a right triangle. A right triangle is a triangle that has 90 degrees as one of its angles. The trigonometric identities of right triangles gives us the relationship between the angles of a right triangle and the side lengths of the right triangle. These trigonometric identities, commonly called SOHCAHTOA, are: sin x = opposite / hypothenuse; cos x = adjacent / hypothenuse and tan x = opposite / adjacent. These identities enables us to find a missing angle of a right triangle given the required side lengths.

If you have ears to hear, hear and understand you are probably one of GODS lost sheep that needs to be found there is this hole in your heart and you tried many times and many things and many ways to fill it and still are but it’s not working and it keeps getting bigger and bigger you would be around multiple people and still feel lonely and work so hard to take those bad thoughts away etc but let me tell you JESUS is the one who can fill that whole in your heart JESUS is that missing piece you’ve been looking for, that peace that’s never ending that true love and joy and happiness it’s in JESUS not of this world but of the kingdom of heaven and if you want to accept him in your heart all you have to do is believe in the gospel A-admit that you’re a sinner and that you need forgiveness, B-Believe that JESUS CHRIST died for your sins and rose again, and C-Confess your faith in JESUS CHRIST and his lordship over your life and you will be saved and this amazing feeling is not a drug it won’t last a couple hours but forever eternally bc it is not of this world but of GOD who sits on the throne of heaven forever and ever HALLELUJAH
