when multiplying scientific notation all you' do is move the decimal whatever times the exponent says or the little number on the 10. Move it to the right when its positive and when its negative move it to the left . I hope that helped :)

What is the length of the missing leg? If necessary, round to the nearest tenth.

Mekhanik [1.2K]

Answer:

The length of the hypotenuse is 36 miles.

Step-by-step explanation:

We can solve for 'a' using Pythagoras theorem. Let's solve it.

39² = a² + 15²
=> 1521 = a² + 225
=> a² = 1296
=> a = 36

Hence, the length of the hypotenuse is 36 miles.

Hoped this helped.

Please help me guys!!! Value of X?

Arturiano [62]

The value of X is 56.66°. The sine of X (opposite/hypotenuse) is 66mm/79mm. When finding angle measurements, you would use sin−1 instead of sin, which is used for finding side lengths. So, X= sin−1(66/79). This then results to 56.66° after using the trig functions in a calculator.
