On the left side you need to distribute that 2 into (x+3). On the right side distribute 3 into (2x+1). Combine like terms and set the entire equation equal to zero, then methodically find x. leave a comment if you need more help.
Answer:
I dont know sorry
Step-by-step explanation:
It's 27 because two negatives cancels each other out.
Answer: 49°, 49°, 82°
<u>Step-by-step explanation:</u>
Let x represent the base angles
then 2x - 16 is the vertex angle.
Triangle Sum Theorem states that the sum of the angles is 180°
(x) + (x) + (2x - 16) = 180
4x - 16 = 180
4x = 196
x = 49
Base angles: x = 49
Vertex angle: 2(49) - 16 = 82
Since EF=FG, you can set 6x - 10 = to 3x + 11

Then add like terms

so,

Now you can divide by 3 to get

:)
then put it back into


so,
