Answer:
21 degrees
Step-by-step explanation:
Triangles have a total angle of 180 degrees.
This makes our equation:
3x+3+4x+135=180
Subtract 135 from both sides and combine like terms
7x + 3 = 45
Subtract 3 from both sides
7x = 42
Divide both sides by 7
x = 6
Plugging the number in:
3x + 3 =
3(6) + 3 =
21
First, add 1.4 to the number given.
-3.2 + 1.4 = 1.4 - 3.2 = -2.2
a.-2.2 is one of your answer
Next, subtract 1.4 to the number given
-3.2 - 1.4 = -4.6
a.-4.6 is your next answer
a. -2.2, a. -4.6 are your two answers
