The answer is 14+35=49 :)))))
The linear equation:
y = k x + b
We will use first two values and solve the system of equations:
11 = k * 7 + b / *(-1)
13 = k * 8 + b
---------------------
-11 = - k * 7 - b
13 = k * 8 + b
----------------------
2 = k
13 = 16 + b
b = 13 - 16 = -3
y = 2 x - 3 ( y varies directly with x )
Hey there!
An equilateral triangle is a triangle that has all equal sides and angles. All the angles in a triangle equal 180 degrees. All triangles have 3 angles. 180/3=60 Each angle in an equilateral triangle is equal to 60 degrees. Acute angles are less than 90 degrees, so: 60<90. This makes every equilateral triangle acute.
I hope this helps!
