Question

Construct triangle abc in which bc = 4.3cm, angle b =45° and angle c =70°

Answer 1

Answer:

55 Is The Third Side

Step-by-step explanation:

Ok So The First Step Is That We Know That Every Triangle Is Made Up Of 180°

(In This Method You Don't Need The Lenth Of The Side)

You Just Have To Add 45° And 70° And Get 115° And Then Just Subtract It From The 180° (Total Lenth Of ANY TRIANGLE) And Get 55 Thus The Third Side Is 55° And If You Add All Of It Together You Get 180 :))
