What is the mean of the measures of the three exterior angles of a triangle if two of the interior angles have measures of 63 an
Genrish500 [490]

Answer:

  1. Mean score=120

Step-by-step explanation:

  1. Areas of a triangle add upto 180degrees (63+78+x=180) 141+x= (x=180-141) x=39
  2. Areas on a straight line add upto 180degrees

180-78=102

180-63=117

180-39=141

  1. 102+117+141=360
  2. Mean=360/3 =120

Sahra is three times as old as her daughter. If the sum of their age is 32. what is the age of the daughter?​
Andrews [41]
So Sahra is 3 times as old as her daugter. That means that the sum of their age is the daughters age times 4.
We can prove that by saying the daughters age is x. Sahra's age must be 3x. Their sum must be x+3x = 4x.
So to get the daughters age we divide the sum by 4, which is 8.
