answer:

22

step-by-step explanation:

5+12-2+7

17-2+7

15+7

22

answer:

b. 78o and 102o

step-by-step explanation:

supplementary angles add to 180 degrees

a. 100o and 90o

100+90 = 190   no

b. 78o and 102o

78+102 = 180   yes

c. 54o and 146o

54+ 146 = 200 no

d. 12o and 78o

12+ 78   90     no   these are complementary

answer:

3√2

step-by-step explanation:

we have to find distance between two points.

we represent a+bi as (a,b) on graph.

hence, 5-2i can be represented as (5,-2).

and 8+i can be represented as (8,1).

by using distance formula, we can find distance between two points.

d=

d=

d=

d=

d=3√2 is distance between (5-2i) and (8+i).
