@dude
If B and C are congruent, you can set them equal to each other
How do I do that?
\[4x+10=x+34\]
Do I multiply or something?
x=8
I think thats how ya do it, simplify both sides
Yep, now substitute 8 back into each equation
Which would be A=8, right?
No, we only solved for x
Oh, how do I substitute again?
For angle B, you would say \[4x+10:~~x=8\\ 4(8)+10\\ 4*8+10\\ =42\]
Try doing that with C (you should get the same answer)
Ohh
42
Yep
Show the steps though, too see if you understand
Well, not much to it but evaluating, 8+34 = 42
Because its (x+34)
yeh, now what is the sum of the interior angles of a triangle?
180
I think its that whether its regular or irregular
Yup, so set the measure of all angles equal to 180 \[42+42+a=180\] Solve for a! That should be your answer!
96
Yep!
Wow, geometry is so perplexing, its like Add this, subtract that, Add this, Divide that, then subtract again, its easy.
Ya lolol
I might need help with some more, but I'll let you know in the future
Maybe inna few min
