The area of a triangle is 180°
Each angle is 60°
Angle 2 is half of 60° which is 30° so it's adjacent angle is also 30°
A right angle is 90°
So 90° + 30° = 120°
Area of a triangle = 180° - 120° = angle 3
Angle 3 = 60°
60 degrees... Considering that this image is to scale and is a regular pentagon, because the dotted line is bisecting the 60 degrees. Making the 60 degrees now thirty degrees, and now you know that the unlabeled angle is sixty because all degrees inside a triangle add up to 180. Now remember how I said that the line was bisecting the angle before? You can see that this is an isosceles triangle... (If you want I can prove that too XD) Meaning that that bisector split the triangle into two congruent triangles... and CPCTC... or Corresponding Parts of Congruent Triangles are Congruent you know that y (that unnamed angle) are corresponding. So 3 is 60

Someone answer asap for ! max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a. the median of max’s data is 250 b. more than half of the data points max recorded were 177 centimeters. c. a data point chosen at random is as likely to be above the mean as it is to be below the mean. d. every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
