Can you help me on this

hope it helps

Step-by-step explanation:

the inside angles of a triangle are always 180 so, 43+60=103+59=162 180-162=18

A=59

B=103

CandZ=18

now we follow the same rule but with the smaller triangles

x=78

y=102

z=18

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

a - base

b - exponent

so,
