The measure of 3 angles in a triangle are in 1:2:3 ratio. what is the measure of the middle angle?

60 degrees

Step-by-step explanation:

1:2:3=180

1x+2x+3x=180

6x=180

x=30

1=30

2=60

3=90

middle=2=60

60 degrees

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

i dont know if you cant find a way its best to actually add all of them start from 105 tho
