The angles inside a triangle add up to 180°
The 3rd angle is supplementary to (6x+1)°
Supplementary means they make a straight line (i.e 180°)
1st angle = 79°
2nd angle = (2x+10)°
3rd angle = 180° - (6x+1)°
180 = 79 + (2x+10) + 180 - (6x+1)
180 = 79 + 2x + 10 + 180 - 6x - 1
combine like terms
180 - 180 - 79 - 10 + 1 = 2x - 6x
-88 = -4x
-88/-4 = x
22 = x
B = √(14² - 9²) = √(196-81) = √115 ≈ 10.7 units
For the first one, it would be 104-14+=x. I'm not sure about the second one, though. Sorry!
Answer:
1 is 6x+4y=422
2 is (12,25)
i dont think 2 is right im really sorry about that- but im like kinda confident for one. i would also check with someone else tho
Answer:
x = 9
Step-by-step explanation:
6x = 54
Simple way of solving, all you have to do is isolate the variable "x." To do that, divide the number, 6, by both sides.
6x / 6 = 54 / 6
54 / 6 = 9
Hence,
x = 9
Hope this helps :)
