solution given:

7x-3=60°[each angle of equilateral triangle is 60°]

7x=60+3

x=63/7

x=9 is a required answer.

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes
