In geometry, an angle is the space between 2 rays (or line segments) with the same endpoint (or vertex). Once you have the correct answer, double check it to be sure. To clear up a math equation, work through each step of the equation slowly and carefully. Next (trust me for the moment) we can re-arrange that into this: And then get our calculator, key in 0.5 and use the sin-1 button to get the answer: Well, the Sine function "sin" takes an angle and gives us the ratio "opposite/hypotenuse". To find the missing angle, subtract the given angle from 180. How can you prove this is true? But I would like it more if I could see the steps when solving the problem. As noted above, a right angle measures 90 degrees. This 180. For example, a triangle always has 3 angles, while a square or rectangle always has 4, and so on. In triangle \( ABC, side a = 9 cm, side b = 10 \text{ cm and side} c = 13 cm\). Supplementary angles form a straight line. The largest angle of a triangle is facing the longest side, C: $$cos C = [\frac{9^2+10^213^2}{2(9)(10)}]$$. Direct link to 's post How to calculate the inve, Posted 6 years ago. Additionally, you can measure angles using a protractor or calculate an angle without a protractor using a graphing calculator.
