Answer:
3
Step-by-step explanation:
3x=9
Divide 3 from both sides to simplify
x=3
Let the angles be A, B, C where B is the second angle.
"measure of the first angle is three times the measure of the second angle" =>
A=3B
"T<span>he measure of the third angle is 55 more than the measure of the second angle</span>" =>
C=B+55
We know that A+B+C=180, =>
A+B+C=180=(3B+B+B+55)
=>
5B=180-55=125
B=25 degrees
A=3*25=75
C=25+55=80
Check: A+B+C=75+25+80=180 ok!
Answer:
(0,-3)(1,-7)(-2,5)
Step-by-step explanation:
-4(0)-3 = -3 --> (0,-3)
-4(1)-3 = -7 --> (1,-7)
-4(-2)-3 = 5 --> (-2,5)
