WebThe area of an equilateral triangle with side length s is s²√3/4. Since we know the areas of these triangles, we can solve for their side lengths: s²√3/4=9√3. s²/4=9. s²=36. s=6. So the … WebExample. Find 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.
