Answer:
y = 22.5
Step-by-step explanation:
Here, the 4 angles shown are all exterior angles of the polygon.
The sum of the exterior angles of a polygon is ALWAYS 360°
<em>So we add up the 4 angles (given in terms of y) and sum it to 360 and solve for y:</em>

y = 22.5
Step-by-step explanation:
7a - 4b = 2b - 5a
7a + 5a = 2b + 4b
12a = 6b
a = 6b/12
a = b/2
I think 20×5=100 then 100÷2
Answer:
yes it is 2/3
Step-by-step explanation:
A foot is 12 inches.
12 can go into 58 evenly 4 times, since 12• 4 equals 48 but 12 • 5 equals 60. This means that the tree is at least 4 feet. Then to find the leftover inches we do 58-48 equals 10, therefore the answer is 58 inches translates to 4 feet and 10 inches.
