Answer: 10
Step-by-step explanation: Calculate the square root of 100
(2x+23)+(9x-5)=95
11x+18=95
x= 95-18/11
x=7
therefore substituting value of x in the given equations of angles:
angle ABD = 2(7)+23=37°
angle DBC = 9(7)-5= 58° Answer
to verify = 37°+58°= 95° ( which was given)
The scale factor changes by 1/8.
The numerator, 1 stays the same; the denominator changes. 16/2 = 8; it is 1/8 the scale of the previous scale.
