0.9 &lt; -r plz help thank you
Komok [63]
0.9 will equal to \frac{9}{10}

Anyhow ! Lets get to the steps!

\frac{9}{10} - r  \leq  ?

\frac{9}{10}

Now "r" will become a negative 

\frac{9}{10} - - r  \leq ?

\frac{-r(10)}{10}

\frac{10(r)+9}{10}  \leq 0

 We have to multiply from each of your sides by the number 10

You  can even divide by the number 10 aswell

Back to the steps

r+ \frac{9}{10}  \leq  ?

Subtract from this fraction \frac{9}{10} to your sides 

This would be inequality r + .900  \leq ?

r \ \textless \   -\frac{9}{10} ← this should most likely be your answer 

Now, Good Luck

given triangle PQR with QR = 8, PQ = 6, and m p = 90 degrees, which of the following choices is used to determine m r
marishachu [46]

The value of the angle R in the right triangle PQR is sin⁻¹ 6 / 8

The situation forms a right angle triangle.

<h3>How to find an angle in a right triangle?</h3>

The angle R can be found as follows:

using trigonometric ratios,

sin R = opposite / hypotenuse

Therefore,

opposite sides = 6

hypotenuse = 8

sin R = 6 / 8

R = sin⁻¹ 6 / 8
