The mean absolute deviation shows the average distance number data is from each other. The bigger it is the farther the numbers are away from each other and vice versa.
Factor x as it is a common factor;
x(8+3)
=11x
15x - 30 = 105 is the mathematical statement
Answer:
right triangle
Step-by-step explanation:
We know that the total angles of the triangle are 180 degrees:
(x) + (4x-10) + (2x+15) = 180
7x - 10 + 15 =180
7x + 5 = 180
7x = 180 - 5
7x = 175
x = 175÷ 5 = 25
Now we calculate each angle
x=25
4x-10= (4*25) -10=100-10=90
2x+15=(2*25)+15=50+15=65
Because we have a right angle, then the triangle is right triangle
