Step-by-step explanation:
A quadrilateral with 4 same-length sides is a <em>rhombus</em>.
(If the corner angles are also 90°, then the rhombus is also a square. That is not the case here.)
__
Adjacent angles are supplementary, so ...
x° = 180° -110° = 70°
Sides are the same length, so ...
2y = y+5
y = 5 . . . . . subtract y
_____
If part of the picture was cut off, the right side of the figure may be something other than 2y. If so, formulate the equation appropriately and solve for y.
Answer:
6

Answer:
Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 93 people in the 18-21 age bracket and finds that 79 of them respond and 14 refuse to respond. When 261 people in the 22-29 age bracket are contacted, 241 respond and 20 refuse to respond. Assume that 1 of the 354 people is randomly selected. Find the probability of getting someone in the 18-21 age bracket or someone who agreed to respond
