Trigonomos spotted a tree across the river and marked the spot directly across from it. Then he walked to

another point 10 meters down the river and found that the angle between his side of the river and the line

connecting him to the tree was 40°.

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.

Which of the following is the best first step in solving the equation below? 4+2㏒³x=17
