24.)True, as long as diagonals are orthogonal
Answer:
44
Step-by-step explanation:
x + (x+2) + (x+4) + (x+6) + (x+8) + (x+10) = 294
Combine all like terms for x and integers
6x + 30 = 294
Minus 30 on both sides
6x = 264
Divide by 6
x = 44
Answer:
x = 73°
y = 39°
Step-by-step explanation:
x + 107 = 180 {Linear pair}
x = 180 - 107 {Subtract 107 from both sides}
x = 73°
y + 51 + 90 = 180 {straight line angles}
y + 141 = 180
y = 180 - 141
y = 39°
