Answer:
45°
Step-by-step explanation:
in straight lines that intersect like this, if one angle is 55°, the one opposite to it will be equivalent. this means (x+10)° equals 55°. then you work out what x is. so x+10=55 so we can subtract 10 from both sides to get x=45°
Answer: 20.5
Form your equation. The formula for perimeter is (2l)(2w) or l + l + w + w, where l = length and w = width.
(l - 5) + (l - 5) + (l) + (l) = 72
Simplify and solve your equation.
4l - 10 = 72
4l = 82
l = 20.5
Since l = length, length = 20.5 and width = 15.5
You can check your work, too:
20.5 + 20.5 + 15.5 + 15.5 = 72
Answer: -12/-5x
Step-by-step explanation: use slope formula which is y2-y1/x2-x1
-7-5/-2-3
-12/-5
And then add x after the slope because slopes have x after them
35/60 = 0.58333333 repeating. So your percent is 58.33% with a bar above the 33 to show it repeats.
