Answer:
SAS is the answer ...........
Step-by-step explanation:
A=8B
A+B=180
8B+B=180°
9B=180°
B=20°
so
angle A =8×20=160°
angle B= 20°
The answer is the first one because you have to multiply the outsider five to the other numbers inside the parenthesis. You don't add them or subtract them because they don't have the same variable
A) x/y = 2/3
B) x + y = 105
Solving Equation A for y
A) y = 1.5x
Substituting A into B
B) x + 1.5x = 105
2.5x = 105
x = 42
y = 63
Answer:
x^3 +x^2 +x+1
