20.Write the equation x = 7 in two variables form​

Answer 1

Answer:

14- We know that the sum of all the angles of a triangle is 180° by angle sum property.let the common multiple be x, so the angles are 2x,4x and 3x. So according to question, 2x+4x+3x=180 x=20 So the smallest angle is 2x= 2*20=40°

15- 1st Quadrant

17- the degree of 2x-1 is 1 as degree is the highest power of a variable in an polynomial. Thus it is a linear polynomial.
