Answer:
B: a number line from 1 to 5
Step-by-step explanation:
Answer:
60
Step-by-step explanation:
12x5 is equal to 60
Let x be the degree of angle a.
Angle b: 20+3x
Angle c: 55+x
We know that all angles add up to 180 degrees.
180=x+(20+3x)+(55+x)
180= 5x+75
180-75=5x
105/5=x
21=x
Angle a: 21 degrees
Angle b: 20+3(21) => 83 degrees
Angle c: 21+55 => 76 degrees
Hope I helped :)
17∠x-11 set up the equation like this
28∠x add 17 to the other side, and you get x is greater than 28
