Question

∆ABC is a right angled triangle in which angle A = 90 degrees and side AB=AC, then find angles B and C​

Answer 1

Answer:

• Step 1 The two sides we know are Adjacent (6,750) and Hypotenuse (8,100).
• Step 2 SOHCAHTOA tells us we must use Cosine.
• Step 3 Calculate Adjacent / Hypotenuse = 6,750/8,100 = 0.8333.
• Step 4 Find the angle from your calculator using cos-1 of 0.8333:
