Answer: x=60 degrees
Step-by-step explanation: This triangle is an equilateral triangle, meaning all angles are equal. Since a triangle is 180 degrees total, 180 degrees/3 angles= 60 degrees each angle.
Answer:
156 centimeters
Step-by-step explanation:
its very simple
8*6.5*3=156
<u><em>Explanation</em></u>
5 students got 6 mark each, 4 students got 7 marks each, 7 students got 8 marks each, 10 students got 9 marks each and 4 students got 10 marks each.
(a) <u>Range is the difference of highest mark and lowest mark.</u> Here, the highest mark is 10 and lowest mark is 6.
So, the range of mark
(b) Total number of students in the group
(c) Mean is the <u>simple average.</u> So, for finding the Mean, we will divide the total marks obtained by all students by the total number of students.
Total marks obtained by all students
So, the Mean mark of the group
Answer: x = -2
<u>Step-by-step explanation:</u>
A line perpendicular to y= (anything) is ....... x = ____
Since it must pass through a coordinate x = -2, y = 0
then the equation of the line is: x = -2
<span>Evaluate for x = 2.
Is it divide by 4?
if so then
Answer is D. 8
(12x + 8) /4
=[12 (2) + 8 ]/4
=[ 24 + 8 ]/4
=32/4
=8</span>
