Substitute the value of x in equation 2. Then you'll get y=3. Then again substitute the value of y in x=1+y, you'll get x=4
The answer is B. First solve the parentheses. Then make a quadratic equation and solve from there.
Answer:
the answer will be 28
Step-by-step explanation:
180-47-31=102
since vertical angles have the same value the top angles for both triangles will be 102 degrees
102+50=152
180-152=x
28=x
Answer:
x=16 x=2
Step-by-step explanation:
x^2-18x+81=49
x^2-18x+81-49=0
x^2-18x+32=0
(x-16)(x-2)=0
x-16=0
+16+16
x=16
x-2=0
+2 +2
x=2
