WebFind the size of angle a° Step 1 The two sides we know are A djacent (6,750) and H ypotenuse (8,100). Step 2 SOH CAH TOA tells us we must use C osine. Step 3 Calculate Adjacent / Hypotenuse = 6,750/8,100 = 0.8333 Step 4 Find the angle from your calculator using cos-1 of 0.8333: cos a° = 6,750/8,100 = 0.8333 WebThe proof shown in the video only works for the internal angles of triangles. With any other shape, you can get much higher values. Take a square for example. Squares have 4 angles of 90 degrees. That's 360 degrees - definitely more than 180.
