Find the value of x in the triangle

x = 28

Step-by-step explanation:

The sum of the angles of a triangle add to 180

85+67+x = 180

Combine like terms

152 +x =180

Subtract 152 from each side

152-152+x = 180-152

x = 28

x=28 degrees

Step-by-step explanation:

180-85=95

95-67=28

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
