The correct answer is 12
Hopes this help.
The formula states that:
Faces + Vertices - Edges = 2
So 21 + V - 49 = 2 => V = 2+49-21 = 30
Answer A!
Logarithmic functions are the inverses of exponential functions. The inverse of the exponential function y = ax is x = ay. The logarithmic function y = logax is defined to be equivalent to the exponential equation x = ay. y = logax
20) triangles equal 180 degrees so if the given is 65 and 50 =115
180-115=65
X=65 degrees
21) your given 34 and 56 = 100
180-100
X=80 degrees
22) the pink square is a right angle. Right angles are 90 degrees. So 90+53=143
180-143
X=37 degrees
23) the two angles you’re given are 25 and 102 = 127
180-127
Measure of angle Q is 53 degrees
