Answer:

13° , 29° , 138°

Step-by-step explanation:

let x be the smallest angle , then

2x + 3 is the middle angle and

2x + 3 + 109 is the largest angle

summing the 3 angles and equating to 180

x + 2x + 3 + 2x + 3 + 109 = 180 , that is

5x + 115 = 180 ( subtract 115 from 180 )

5x = 65 ( divide both sides by 5

x = 13

2x + 3 = 2(13) + 3 = 26 + 3 = 29

2x + 3 + 109 = 29 + 109 = 138

the 3 angles are 13° , 29° , 138°

Complete the function table below function<br> f(x) = 6x -3
taurus [48]
When x is equal to -1:
f(-1)=6(-1)-3
=-7-3
=-10
y=-10

When x is equal to 0:
f(0)=6(0)-3
=0-3
=-3
y=-3

When x is equal to 1:
f(1)=6(1)-3
=6-3
=3
y=3

When x is equal to 2:
f(2)=6(2)-3
=12-3
=9
y=9
