Answer

B. 105

Step 1: የሶስት ማዕዘን ውስጣዊ ማዕዘኖች ድምር 180∘180^\circ መሆኑን እንጠቀማለን። የተሰጡት ማዕዘኖች 35∘35^\circ, 40∘40^\circ እና x∘x^\circ ናቸው። 35∘+40∘+x∘=180∘35^\circ + 40^\circ + x^\circ = 180^\circ

Step 2: የታወቁትን ማዕዘኖች አንድ ላይ እንደምር። 75∘+x∘=180∘75^\circ + x^\circ = 180^\circ

Step 3: የ xx ዋጋን ለማግኘት ከ 180∘180^\circ ላይ 75∘75^\circ ን እንቀንሳለን። x∘=180∘−75∘x^\circ = 180^\circ - 75^\circ x∘=105∘x^\circ = 105^\circ ስለዚህ የ xx ዋጋ 105 ነው።

ከቀረቡት አማራጮች ውስጥ ትክክለኛው መልስ B ነው። B. 105\text{B. 105}
