Question

Find the unknown angles in triangle ABC for each triangle that exists. B = 138.4°, c = 7.1, b = 15.5 Select the correct choice below, and, if necessary, fill in the answer boxes to complete your choice. A. There are two possible sets of remaining angles. The measurements for when A is larger are A? = ?° and C? = ?°. The measurements for when A is smaller are A? = ?° and C? = ?°. (Round to the nearest tenth as needed.) B. There is only one possible set of remaining angles. The measurements for the remaining angles are A = ?° and C = ?°. (Round to the nearest tenth as needed.) C. No such triangle exists.
