What is the value for x if the perimeter is 45

11

Step-by-step explanation:

Perimeter of the triangle = 45

x + x + 7 + x + 5 = 45

3x + 12 = 45

3x = 45 - 12

3x = 33

x = 33 /3

x = 11

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153
