Which of the following triangles is not possible? A = 75o , 15o , 90o

B = 90o , 30o , 60o

C = 60o, 60o, 60o

D = 100o, 45o, 45o

100, 45, 45

Step-by-step explanation:

45 + 45 is 90 not 80 for 180

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

x = 23.78
