Question

construct a triangle ABC in which angle b is 30degree BC is 6 cm AB+AC is equal to 11 cm​

Answer 1

Answer:

Angle B = 90 degree

Because,

The larger side is AC = 12cm

Therefore, apply pythagorean theorem

AC^2 = AB^2 + BC^2

12^2 = ( 6 root 3 )^2 + 6^2

144 = 108 + 36

144 = 144

In the pythagorean theorem, if LHS = RHS then the angle opposite to the larger value of the side should be 90 degree, According to Converse of pythagorean theorem studied in class 10

Answer 2

Step-by-step explanation:

Draw a line BC=6cm

2. Construct 30

o

at B. Extend BP.

3. Take 3.1cm on compass, cut an arc on BP. Join CX.

4. Take perpendicular bisector of CX. It intersects with BP at A. Join AC
