The mean height of the students in Marta's class is 60 in. There are 18 students in her class. Write and Solve and equation to f
Mashcka [7]

Solution: Let x be the height of a student in Marta's class.

The mean height of 18 students in Marta's class is 60 inches

We know that:

Mean = \frac{\sum x_{i}}{n}

60 = \frac{\sum x_{i}}{18}

60 \times 18 = \sum x_{i}

\sum x_{i} = 1080

Therefore, the total measure of all 18 student's heights is 1080 inches

What is the exterior angle of triangle ABC<br><br> These are the points:<br> A=3, B=10, C=6
igor_vitrenko [27]
Based off of  what I can see in the  photo (its too blurry to know for sure) and what I think you're asking:

The angle of a triangle always adds up to 360degrees, so base it on that and the acute and obtuse  angles  and get the degrees from there, the angle would be those degrees you find or <10, 5, 4 (what I assume  is a 5)
