Answer:

  1. 48°
  2. 60°
  3. 72°

Step-by-step explanation:

The sum of ratio units is 4+5+6 = 15, so each unit stands for 180°/15 = 12°. Multiplying the ratio units by 12° gives the angle values:

  4×12° : 5×12° : 6×12° = 48° : 60° : 72°

Angles 1 to 3 are 48°, 60°, 72°, respectively.

Y+3=2(x+5), write the equation of the line in slope intercept form.
Alex

Answer:

slope intercept form: y=mx+b

y+3=2(x+5)

step 1: use distributive property

y+3=2(x)+2(5)

y+3=2x+10

step 2: subtract 3 on both sides to make y by itself

y+3=2x+10

-3 -3

final answer: y=2x+7
