I’m not sure what the question is but I’m just gonna assume that you need the equation: y=1/2x+5
Answer:
it's used in conjunction with variance
tan( 31 ) = x / 39
0.600860619 = x / 39
x = 0.600860619 × 39
x = 23.433564141
______________________________
Round to the nearest tenth :
x = 23.4
Round to the nearest hundredth :
x = 23.43
