Finding angles in a right triangle
WebIn a right triangle, one of the angles is exactly 90°. Such an angle is called a right angle. To calculate the other angles we need the sine, cosine and tangent. In fact, the sine, … Webtan θ = opposite/adjacent. tan θ = 6/8 = 0.75. θ = tan -1 (0.75) Using the calculator, θ ≈ 37° (Rounded to the nearest integer). Answer: The angle at C is, θ = 37°. Example 3: Find the angle at vertex A in the following triangle using one of the formulas for finding angles. Round your answer to the nearest tenths.
