Triangle angles always add up to 180 degrees.
So what you’ll need to do is add up all the angles and set them equal to 180. And then solve for x
4x+3x+2x=180 | Add up all values
9x=180 | Divide 180 by 9
x=20 | There’s your answer
HOPE it helps!!!!!!!
plz mark as a brainliest answer!!!!!
6 consecutive even numbers
First x
Second x+2
Third x+4
Fourth x+6
Fifth x+8
Sixth x+10
126=x+x+2+x+4+x+6+x+8+x+10
126=6x+30
Subtract 30 from both sides
96=6x
Divide both sides by 6
x=16
Fourth x+6=16+6=22
4a²b⁴ - 25x⁶y⁴
(2ab²)² - (5x³y²)²
= (2ab² + 5x³y²)(<span>2ab² - 5x³y²) By difference of two squares</span>
102- you need to divide 2,142 by seven (for the seven dollars per ticket) then divide by 3 (for the 3 days).
