Answers

16.76

Explanation: Since you are rounding to the nearest hundred, your answer will have 2 digits after the decimal. When the third digit is equal to or greater than 5, you round up previous digit. If the third digit number is lower than 5, you leave the the previous digit as it is.

In this case, the third digit is the number “8” and since it is greater than 5, you round up the digit before it. The 16.7[5]8 turns into 16.7[6].

Hope that helps!

35.54 degrees

How I got this

tan(angle) = opposite/adjacent

tan(A) = BC/AC

tan(A) = 5/7

A = arctan(5/7)   apply the inverse tangent, same as arctangent

A = 35.5376778 ... make sure your calculator is in degree mode

A = 35.54 rounding to two decimal places
