Answer:
15√2
Step-by-step explanation:
Tan 45° = 1, and tan = (opposite side)/(adjacent side)
We can set up an equation as follows...
tan 45° = x/(15√2)
Solve it...
1 = x/(15√2)
multiply both sides by 15√2 to isolate 'x'
15√2(1) = (15√2)x/(15√2)
15√2 = x ( the 15√2 in the numerator and denominator cancel out)
Answer:
240
Step-by-step explanation:
Using the straight line formula; y=mx+c, take two points, for example, (4, 80) and (5, 100)
m=change in y/change in x, so;
m=(100-80)/(5-4)= 20
Take point (4, 80)
80=20×4 + c
80-80=c=0
so y=20x
y=20×12=240
