Can you help me pls with this one :/

Angle BEC is also 45 degrees.

Step-by-step explanation: This is because the opposite and congruent angle of BEC is 45 degrees. Congruent means the same. Therefore, Angle BEC is 45 degrees.

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set

see explanation

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
