Question

4.Can we cut of a triangle of one side 7 cm and one angle 40⁰ from a circular sheet of diameter 10 cm. Justify your answer. (sin 40 =0.64)

Answer 1

Step-by-step explanation:

Given 4.Can we cut of a triangle of one side 7 cm and one angle 40⁰ from a circular sheet of diameter 10 cm. Justify your answer. (sin 40 =0.64)

• The diameter of the circumcircle of a triangle with one angle of 40 degree and its opposite side will be 10 cm = 7 / sin 40
• Sin 40 is given as 0.64
• Now 10 cm = 7 / 0.64
•                      = 10.93 cm
• Diameter of the paper is 10 cm and it is less tvan 10.93 cm. Therefore triangle cannot be cut out
