Referring to the Fig. in Question #40, find the unknown<br> length Y.
icang [17]

Answer:

tan30°=7/x

\frac{1}{ \sqrt{3} }  =  \frac{7}{x }  \\ x = 7 \sqrt{3}

cos30°=x/y

\frac{ \sqrt{3} }{2}   =  \frac{7 \sqrt{3} }{y}  \\  \\ 7 \sqrt{3}  \times 2 =  \sqrt{3}  \times y \\ \frac{7 \sqrt{3 }  \times 2}{ \sqrt{3} }  = y \\7 \times 2 = y \\ 14 = y

tell me if it's wrong.

Solve the equation with the problem set {-28,-8,8,28} |10-x|=18
Elden [556K]

Answer:

{-8,28}

Step-by-step explanation:

|10-x|=18

The absolute value has two solutions, one positive and one negative.

10-x = 18   and 10-x = -18

Subtract 10 from each side

10-10-x = 18-10     10-10-x=-18-10

-x = 8                     -x = -28

Multiply each side by -1

x = -8                      x = 28
