Each isosceles triangle had the same vertex angle as triangle EJF. The sum of the vertex angles
equals 180°. (2 points, one for the correct equation, one for the correct solution.)
Let x = the number of isosceles triangles.
Fill in the equation with your answer from Q12 and solve for x.
x = 180

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
