Factoring out the 1/2 (that is the coefficient of the variable) would require you to divide the equation by one half, which is the same as multiplying by two. After doing this, the answer can be expressed as:
1/2 (d+12)
Answer:
65 degrees
Step-by-step explanation:
If the angle at the top there is 35 degrees, then the angle directly underneath is also 35 degrees, and the angle of 80 degrees is given, and 80+35=115, and the sum of the angles in a triangle is 180, and so 180-115=65. 65 degrees=x
