I agree with the first answer posted
The sum of these two angles is 180°, therefore,
138° + (x + 8)° = 180°.
Simplify the left side of the equation.
146° + x = 180°.
Subtract 146 from both sides.
x = 34°
Answer: 4x^2 +4x+3
Step-by-step explanation:
Answer:
The answer is 4x(exponent of 2)
Step-by-step explanation:
First you have to combine like terms, which are x and -.49x. You then get 0.51x. The equation now becomes .51x=5045.53. You then divide .51 on both sides. On the left you are left with x and on the right you are left with x=9893.19608.
