Answer:
Step-by-step explanation:
perimeter of rectangle = 1100
let breadth be x
length = 300 + x
perimeter of rectangle = 2(l + b)
1100 = 2(300 + x + x)
1100 = 2(300 + 2x)
1100 = 600 + 4x
1100 - 600 = 4x
500 = 4x
500/4 = x
125 = x
therefore breadth is 125 feet
length = 300 + 125
=425 feet
The measure of ∠ROU is 94°. That is a central angle, which means that the arc it intercepts also measures 94°. Because ∠SOT is vertical to ∠ROU it is also a 94° angle with a 94° intercepted arc. The other 2 angles, ∠SOR and ∠TOU are vertical and have the same measure, both the angles and their intercepted arcs. Those measures will split the difference of 360-94-94, which is 172. 172/2 is 86. That means that those arcs also measure 86. Arc SRT is the addition of arc SR, RU. and UT, which are 86+94+86, respectively, which add up to 266. Second choice down.
