Question

how to construct a triangle ABC in which a b is equal to 7.4 CM angle BAC is equal to 47 degrees angle abc is equal to 68 degrees​

Answer 1

Answer:

Find <C. Then use the law of sines to determine the length of the other two sides. Then-

1- Construct a ray AX.

2- On the ray AX, mark point B such that AB=7.4cm.

3- Taking A as centre and radius 7.6 cm(found using the law of sines) construct an arc.

4- Taking B as centre and radius 6 cm(found using the law of sines) construct another arc which intersects the previous arc at the point C.

Then you will get your required triangle.
