Method 1: The forces on each charge lie along a line connecting the charges. Let the variable d represent the length of a side of the triangle. Since the triangle is equilateral, each angle is 60o. First calculate the magnitude of each individual force. Now calculate the net force on each charge and the direction of that net force, using ...

The cosine ratio can be used calculate an unknown angle or and unknown side in a right triangle. To find the either of these unknowns the adjacent side and hypotenuse are used from an angle of reference. Example. Suppose we use (A as the angle of reference then: Cosine always used the hypotenuse and adjacent sides of a right triangle. C. osine ...

Simplify. You may use a handheld calculator (in degrees mode) to calculate.In this case, an approximate value for the tangent of 38 degrees is 0.78129: Step 9: Check for reasonableness: In this case, the acute angle was 38°, which is. less than 45°. (If it had been a 45° angle, both legs would be congruent.) It is

The Law of Sines works just as well if the side c is given instead of the angle C. In that case, we solve for sin(C) and then use the inverse-sine function to calculate the angle C. Example 2: Find the size of angle A in the illustrated triangle: C=79(, a=36 mm, and c=50. mm. Considering significant digits, the final answer is A = 45

Have students choose one triangle created by the transversal and, without measuring, calculate all of the exterior angles. Then have them find the sum of the exterior angles. [360°] Have them answer whether the sum of exterior angles would always be the same regardless of a triangle’s interior angle measurements. [yes] Closing Activity
