Question

Construct a triangle ABC with BC = 6.5 cm, AB = 5.5 cm and AC = 5 cm. ∠BAC is _____.

• A. ${86.5}^o$
• B. ${76.5}^o$
• C. ${66.5}^o$
• D. ${56.5}^o$

Answer 1

The correct option is B

${76.5}^o$

∠BAC is ${76.5}^0$.

Step 1: Draw a line, AC, 5 cm long.
Step 2: Cut an arc AB= 5.5 Cm with A as the center.
Step 3: Cut an arc CB= 6.5cm with c as the center.
Step 4: Mark, B, the point of intersection of the two arcs.
