you can use any trig tool to determine an unknown side length. If you know the length of the longest side of a right triangle and all the angles: you will need to use the inverse tangent. using the sine ratio MUST be your only next step. you cannot use tangent for your next step. Given the diagram here, choose the correct next step. label your diagram then choose tangent to start use pythagorean theorem to calculate the height the question is impossible to complete label your diagram, choose cosine to start Triangle GHJ is a right triangle. J = 80o You would need to use "sine" to calculate a side. Triangle GHJ is obtuse. You have triangle GHJ where G = 77o and H = 23o .What conclusion can you make? To calculate the diagonal distance to the ship, use tangent. add the two heights then use sine to find the diagonal distance You need to use cosine to calculate the diagonal distance. Given the diagram shown, choose the correct statement. give up - not enough info to do anything. You know two sides of a right triangle and you want to know another angle value.Which is the MOST correct statement? tangent is certainly the best option. use cosine. use the table immediately. you will need to use the inverse function. 7.0/5.2 7.0/8.7 5.2/7.0 5.2/8.7 Given this triangle, which ratio is tan A? 10.5/22.1 9.5/22.1 9.5/10.5 22.1/10.5 Given this triangle, which ratio is cos U? |
