Answer:
z is obviously 60 degrees, there are 180 degrees so it has to be 120
Step-by-step explanation:
x = 120
Answer:6
957 - 249 = 708
The number that goes above the 5 is 4
Number above the 7 is 17
The ansa is 256=(12+x)(12+x)
4(-3 + -2d) = 12
(-3 * 4 + -2d * 4) = 12
(-12 + -8d) = 12
-12 + -8d = 12
-12 + 12 + -8d = 12 + 12
-12 + 12 = 0
0 + -8d = 12 + 12
-8d = 12 + 12
12 + 12 = 24
-8d = 24
d = -3
