Answer 1

Step-by-step explanation:

it is equilateral, so all angles of triangle are equal to 60. so you set the equation 7x- 3=60. You add three to both sides to get 7x=63. Then you divide both sides to get x=9. Your final answer is 9.

Answer 2

Answer:

solution given:

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

7x=60+3

x=63/7

x=9 is a required answer.
