les areknown, to find the remaining two sidesand angle. 2. When two sides and their includedangle are known, to find the other sideand other two angles. 3. When only the three sides areknown, to find all three angles. 4. When two sides and the angle opposite only one ofthese sides is known, to find… … 178 MECHANICS AND ALLIED SUBJECTS angle B = 80^ and side a = 30. To find angle C andsides b and c we proceed as follows: In every triangle the three angles added togetherequal 180°. Therefore angle A + angle B + angle C =180°. But angle A = 75° and angle B = 80°. There-fore 75° + 80° + angle C =…
