Tan 30= 6/x

Cross multiply

Xtan30= 6

X= 6/1/square root of 3

X= 6 x square root of 3

X= 10.39 ~ 10.4

What percent of a foot is 8 inches? Show your work.
BaLLatris [955]

Answer:

66.67%

Step-by-step explanation:

We know that a foot is equal to 12 inches.

First, we write it in the form of a fraction.

8 inches of a foot = 8/12

Then we simplify the fraction.

8/12 = 2/3

After that, to write the number in percentage form, we need to multiply the fraction by 100%.

2/3 x 100% = 66.67% (Nearest hundredth)
