Answer:

4. x = 16.8

5. x = 35.98

Step-by-step explanation:

For both triangles that you need to work on, use the trigonometric function which is tan and you are dividing opposite by adjacent for the answers.

For number 4, the equation you are setting up is tan 35 = x/24. Multiply 24 on both sides to get the answer which is 16.8 for the x side.

For number 5, the equation you are setting up is tan 17 = 11/x. As a result on your calculator, you should get 35.98 for the x side.

a square with an area of 144 cm² is reduced by a factor of 1/3 how long are the new sides of the square?

olga55 [171]

Answer:

4 cm

Step-by-step explanation:

The square root of 144 is 12 (12 x 12 = 144) so we know our sides of the square are 12 cm²

12 / 3 = 4

( $\frac{12}{1} x \frac{1}{3}$ )

The sides of the new square are 4 :)

Hope this helps and is correct, have a nice day! :D
