Answer:
x = 13
y = 18.38
Step-by-step explanation:
tan 45 = x/13 (tangent = opposite / adjacent)
1 = x/13
multiply both sides by 13
x = 13
cos 45 = 13/y (cosine = adjacent / hypotenuse
0.7071 = 13/y
multiply both side by y
0.7071y = 13
divide both side by 0.7071
y = 18.38
Let the equation be 1/2x=48-10
where x is the dad's weight
1/2x=48-10
1/2x=38
x=76 ( i divided both sides by 1/2)
F(x)=x-4
