Solve for x. 4 48 X 14<br>can someone solve this for me please? ​
Vikki [24]

Answer:

sure, the answer is 50

Step-by-step explanation: Because this is a right triangle, you can use the pythagorean theorem, which is a^2 + b^2 =c^2 so you square 48 and add it to 14 squared and then take the square roo t to get the value of the hypotenuse, note that c will always represent the hypotenuse or longest side, and that pythagorean theorem can only be used on right triangles

Trigonometry question
ehidna [41]

Answer:

The scale factors that make figure smaller are the option D. -0.5 and the option E. 0.25

Step-by-step explanation:

we know that

If the absolute value of the scale factor is greater than 1, then the image will be larger than the pre-image.

If the absolute value of the scale factor is less than 1, then the image will be smaller than the pre-image.

If the absolute value of the scale factor is equal to 1, then the image will be the same size than the pre-image.

Additionally, a negative scale factor causes the dilation to rotate 180 degrees

therefore

In this problem

The scale factors that make figure smaller are the option D. -0.5 and the option E 0.25
