Answer: 5.4
Step-by-step explanation:
Use cosine to find the adjacent side.
cosine = adjacent/hypotenuse
Substitute these values in the cosine equation:
cos(39) = x/7
7*cos(39) = x
Use a calculator to find the value of x:
x = 5.4
Step-by-step explanation:
2.5 + 0.15p = 0.4p
0.25p = 2.5 (subtract 0.15p on both sides)
p = 10 (multiply 4 on both sides)
