Determine the missing angle. you in advance!

The answer is 72.

Step-by-step explanation: The reason why the other angle across is the same is because they are vertical angles which means they are the same when they are across each other.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

the answer to the expression is 83
