Answer 1

Step-by-step explanation:

Steps to create the required triangle:

1. Draw a straight line of length 7.8cm. Name the two ends B and C respectively.
2. Extend a line from point B at an angle of 45°, using compass.
3.  ∠C = 180° - ( ∠B + ∠A) = 180 - (60 + 45) = 75°. Extend a line from point C at an angle of 75°, using compass.
4. The point at which line from point B and line from point C intersect will be point A.
5. Join A and B, and, A and C.
6. Thus the required triangle is formed now.

That's all.
