Division. You can divide 64 by 3 to find q.
-3(2x+y) im not great at this but you can checm if its right or not
Answer:
y = 22°
Step-by-step explanation:
the sum of the interior angles of a triangle is 180 degrees
40 + 2x = 180
2x = 140
x = 70
'x' and '5y' form a linear pair, meaning they add up to 180 degrees
x + 5y = 180
substitute 70 for 'x'
70 + 5y = 180
5y = 110
y = 22
Step-by-step explanation:
lets take a look....
In order to find the perimeter of a triangle you have to get the sum of all sides. In other words,
